Sorry about all the harshness you've been receiving here. My impressions/advice --
You have a friend/lover who you've known for several years. You're planning to do a trial move-in with the possibility of a long-term commitment (marriage). You have an open relationship, and both have the freedom to get involved with other people emotionally and physically, but right now neither of you is involved in any other serious emotional relationships, just a number of physical ones. Your other involvements take the form of casual sex, hers take the form of informal sex work (no judgment whatsoever implied by calling it sex work -- I know it's easy to say that, but I actually mean it --that just seems to be what it is, exchanging sex for money). You're concerned as to whether or not you can form a deep bond with this person in the context you've created for yourselves, or whether her involvements with other people will keep you from emotionally committing to her. You also worry whether she's truly willing/able to commit to you.
Sound right?
I think there are a few things to consider here.
1) Three months may not be enough time to decide whether a serious commitment is a good idea. People can still be on their best behavior for the first few months of a relationship -- you don't usually *really* get to know them, warts at all, until a little further in. I imagine this is true also for a major shift in a relationship -- you may get to see the best side of her as a roommate/partner in those three months, and then find that things change down the line. Why not just plan to live together for as long as it makes sense for both of you, and leave the serious commitment for when it really feels right? What's the rush?
2) If you do decide that a serious commitment is what you both want, marriage may or may not be necessary. Marriage ties you to another person legally. If you don't think of it as a religious thing, then the legal aspect is the ONLY difference between marriage and any other type of commitment ceremony. Is being legally tied to another person, half your property being theirs, etc., really right for you two? Why? That takes a HUGE amount of trust and, if it doesn't work out, you two will be able to really screw each other over if you're married (divorce proceedings!). I'm not saying it couldn't ever be right, but if you're still having such fundamental doubts, I would hold off on making anything legal until years down the line. I just don't see what benefit it would confer to either of you, and I worry that you're considering it mainly because it's what society tells you a committed relationship has to look like. Not true.
3) Are you truly ok with an open relationship? This is where your most serious questions seem to be. There are two parts to this.
3A) Are you ok with her being with other people on an emotional level? I'm thinking of this thing you said -- "She makes statements sometimes that send a ping of pain into my body. One recently was her talking about another guy and she said something akin to "yeah i think he is worth the effort, i actually like him, hes probably the only one in the world i would put that much effort in for." She is not being cruel in telling me this... we are just really solid friends and shes being honest...this is her bf that dumped her.".
It sounds like this really hurt you. I can see why -- "the only one in the world" makes it sound like she puts him above everyone else, even you... again, why would you marry someone, which you can only do with ONE person in the world at a time under our legal system, when you're not their #1 priority. So there's that question, about this specific guy -- does she really care about him more than you, would she leave you for him if he asked? But then there's the more general question, how would you react if she didn't put him above you, just on an equal plane, but wanted an equal emotional relationship with him or with someone else? This is where "polyamory" actually enters the picture. Do you believe that people can have functional, honest, respectful, loving relationships with more than one person? Do you believe that you and she have the communication and time-management skills for that? There are some great writings at www.morethantwo.com that might help you feel out whether this is a path that makes sense for the two of you.
3B) Are you ok with her being with other people on a physical level? You said -- "Today i messaged her something random and she replied "I'm getting fucked as i write this lol." It hurt and my natural inclination is to care less about her and pull my emotions away." If she's doing sex work (which, again, is what being a gold digger seems to be to me, if in a more informal way), being physically intimate with other people is part of her every day experience. It's what she's chosen to make her happy and to pay her bills. You need to be able to accept this 100% in order to be with her. If you find that it makes you pull away and grow cold, then, no, I'm sorry, this is not going to work unless you can find a way to get over that. This video may be of help to you --
4) Is she the right one? Let's say you work out all of the issues above. That still doesn't mean this is the right relationship for you, necessarily. You say -- "I love her a lot but I feel like she doesnt love me the same way... i think i would give up alot for her... but she woudlnt me... and so i think my pulling away emotionally and not wanting to marry her is justified..."
Does she love you as much as you love her, would she sacrifice for you like you would for her? These are crucial questions. Don't go jumping into anything without knowing the answers... there's no big rush!! Take the time to really learn her heart and mind. ASK her these questions, and, better yet, pay close attention to her actions, how she treats you. When something is important to you and she needs help, but it would be inconvenient for her to be there, does she do it anyway?
And then you say -- "but hten i also feel marrying her and sleeping with other women on the side would be a baller situation that i would like... and if id idnt i would miss out on a lifestyle id enjoy logically... I'm so confused.....
Make sure that you're not just doing it because it makes sense "logically". Your gut has to agree with your head, or you'll be miserable in short order. What makes you think you couldn't have this "lifestyle" -- a committed, caring relationship and casual encounters on the side -- unless you make this particular commitment to this particular women? What you're describing actually isn't that uncommon. Call it polyamory (which would be the right word if you're open to forming emotional bonds with other people), call it swinging, call it an open relationship, it's everywhere. Don't jump into something that feels wrong because you think this is your last chance to have the life you want.
Good luck!!!!
Thank you for all this advice. Um... there is something I should have mentioned. She isn't a U.S. citizen, so we will be having 3 months to decide if we want to marry.
There are certainly multiple parts of me, which makes us complicated as people. I'm not exactly okay with her seeing other people, but I'm also not okay with us being only together. I would not be happy if I could only see her. lol
She told me recently that she has been fucking this guy for a long time, over a year, and she emotionally always wants him, like no one she has ever been with, but he also emotionally manipulates her. She also said she could be with him if she wanted to, but she is choosing to come and be with me and leave him. But the fact that she has fucked him for so long leaves her emotionally closer to him, even though she is making the choice to not be, and to be closer to me.
She also told me recently she would give up being a sugar baby for me if I wanted her to. She was doing it as a way for me and her to be together, because before she couldn't handle the idea of being with me while I was with other women. But it is something she wants to do. I didn't know this when I wrote the original post. It does make me feel like she would give up a lot and really cares about me, etc.
I mean, I care about her more than she cares about me right now, but she has cared about me more than I cared about her in the past.
Hmm... I don't feel like it's my last chance or anything. In fact, I feel like I could probably find someone better if I waited. But I think it's a good time for me in my life to kind of make house with someone, and find the woman who's going to be most important to me. I think she has a huge potential to be that, more than most women I have met.
