Really good if talking here is helping you get the thoughts out and is allowing you to be present with your wife. I very much hope that you are no longer talking to her about poly, other relationships and about your own emotional state. The time to be worrying about all of those things passed when you and your wife were attempting to get her pregnant and were long passed at the point she was pregnant.
Reading back through your first post, it doesn't seem to me as if there are any indications that your wife has any interest in a relationship structure other than monogamy.
Your wife suggested you find another woman and move on. This isn't at all the same thing as her being up for living in any kind of open structure. In May, she wanted an easy way to end the marriage - and you finding somebody else would have provided that.
In spite of things clearly being difficult between you and your wife in May, you both continued with attempts to get pregnant and these attempts worked this time. Now you are faced with a change in your life that will last a lifetime and will take focus away from you, your wife and your needs - transferring the family focus to the baby. There will always be an amount of focus on parenting for the rest of your lives. This is a massive change and it sounds like you have both entered into it from a less than ideal position.
So now it sounds as if you are worrying about what you will lose. There is understandable regret at moving on in life and feeling as if opportunities to experience what you have not will be harder to come by. This is not at all uncommon. Over the years I've been a member here, I've seen loads of pregnant women who are upset that their partner has suddenly discovered poly as the pregnancy has progressed. Plus some men like yourself who seem to become fixated on it once their partner is pregnant.
To make matters worse, you broke agreements with your wife and did things that you have agreed not to do.
So - your wife was never really into an open relationship. The first chance you get, you break her trust. Now she's pregnant.
You are still going on about open relationships.
I'd say that it's pretty much a non-starter.
If I were in your shoes I'd get whatever counselling and help I needed to put poly out of my head and get myself fully invested in the family that I'd helped to create.
There is absolutely no need for you (or anybody else in the Western world) to have children. Creating that kind of relationship is a deliberate choice and it does put limits on what else you can do. You chose freely to do this - own that choice. Learn the skills you need to parent well. Learn about how children learn, how best to support them when things aren't going well, how to negotiate the school system with your child, what things there are in your area to take kids to, how you and your wife will best work together as parents.
There is so much to learn and so much growth to be done for parents.
You may be going to appointments with your wife and helping around the house just now - but in filling your mind and spare time with thoughts of romance, you are still short changing your unborn child because helping your wife out doesn't help you learn about children - and once the baby is born, sleep will be short and life will be hectic.
IP
I am with IP on this. My ex husband did this when I was pregnant, but he preyed on my sensitive feelings for a woman, that I wasn't interested in at the time of my pending daughters birth, of having a full blown relationship with. Like you he had cold feet on being a parent and thought, by 1) we have problems, let's add a person to it (child), and then 2) omg, child isn't working let's add another (woman I liked),.
Then difference between you and him though, is that we were 18/19 with littler understanding about how the world worked, or knowing our options. We didn't think it was an option for abortion or adoption, and I certainly didn't realise it was an option to tell him, no stop pushing this woman on me while I am pregnant.
You are not 18. You have been trying a long time to have kids. Your behaviour is disgusting. If I were your wife, I'd be planning an adoption or abortion based on your really selfish and immature behaviour that is not suited towards rearing and raising a kid. And yes you can all hate me for being brutally honest, but kids are a long term, serious commitment, with huge social and legal ties, and if you have issues with poly now, it's only going to be magnified later, to the point of you losing everything. That's a real possibility. She could walk into a divorce now, taking kid, money, home, your self respect, your social status at work, and community, and that's not even considering the heart ache and loss of herself, or your unborn child. Those are realities just from your blog here. Those are your legal relaities as to her it could be used in court as cheating. Plus everything you write here, pseudonym or not, can be tied back to your IP address, and legally proved as cheating. Is texting penny really worth that?
I don't think this is about penny at all. I think this is about losing your freedom. Being committed to just maybel and kid(s) for the next 20 years. About the responsility and loss of freedom that evokes. So yeah poly is going to look pretty damn appealing right now.
You talk a good talk on here, but you're not walking the walk of Ethical poly, which is the consensus of all involved. If she isn't a joyful hell yes, I would leave, or stop pushing it. Or at least show her her options and have the talks you need to have if you're going to value freedom over family. I would say that's what you need to sort. Not seeing penny, if your freedom is more important that having and raising a child you have created intentionally.
Have you once considered how this will affect that baby? How this will affect maybel? Right now maybel is vulnerable in her pregnancy. Her body isn't her own, her life isn't her own, her drive to protect that child goes beyond anything you may want right now.
And what about that kid? The child doesn't get to choose their parents. And you're saying, from the outset to this child, no verbally, I value seeing romantic relationships over you kiddo. I am not thinking about baseball, and your room decorations, of singing sign classes, or relating to new dads and how they cope, or what your college fund looks like...I am thinking I want to txt some woman I just met more than meeting and building my relationship with you and mummy.
That's what your actions are telling me, and a lot of people on here and that's why we are so disgusted.
