Words were actually my top love language when I took the quiz years ago... But I think the Dag experience messed with that

His words did not match his actions, and eventually I started to believe "talk is cheap". Now when Castle says he misses me, my gut reaction is to see the words as scraps he's throwing my way to avoid having to put in actual effort.
And that's unfair. Castle isn't Dag. This relationship isn't that relationship. I know that, but... The heart takes a while to bounce back, I guess.
These last few days have been a good opportunity to really face my fears, though. Dig down and say, what hurts me about that? why is that scary?
I think I've talked about this before, but I never had the "typical" new-to-poly fear that my partner would meet someone better and leave me. One, it seemed like that was just as likely (if not more so!) in a monogamous relationship. Two, a breakup would be awful and painful but survivable. Even if Andy left me, i would still be ok. It would hurt and I would be sad and angry, but I wouldn't die, you know? So I never felt that particular fear.
Yet there was, and still is, so much anxiety and fear around poly, and it's always been sort of nebulous and hard to explain. I looked back and it has come out before in this blog as "my partner will talk about me with his other partners" and "my partner will like his other partner better but not break up with me". I'm still searching for the right words to explain it, but...
Did you ever have a back-up friend? One who you didn't really care about that much but they were always free, or always had money to go out, or would go along with whatever you wanted to do? So you'd do stuff with them when your real friends were busy... Invite them to things occasionally... Basically give the "friendship" just enough effort to keep them around when you were bored?
Or did you ever know someone who has that one sure thing booty call? They would never publicly date the person, they'd only hit them up if they had no better options that night, but there was Mr. or Ms. Booty Call, always waiting by the phone.
My ultimate fear is being the girlfriend version of the back-up friend or the sure-thing booty call.
Like, what if my boyfriend mentally ranks his partners, and I'm last? Even worse, what if everyone knows that but me? What if they're all snickering behind my back that I'm head over heels in love with this guy who doesn't care that much? What if he's just keeping me around because it doesn't cost him anything so why not?
I never worried about that in mono relationships because... Well, if you only get ONE partner, you're going to choose someone you like. As long as I was the official public girlfriend - and later, wife - I figured my guy actually wanted me. But poly - there's nothing stopping anyone from having all the partners they want, so why wouldn't they keep a few "spares" around?
So that's my fear. The fear that gets triggered when I see my partners spending lots of time and energy on their other relationships. That I am just the bottom of the heap, not worth the effort, in-case-of-emergency girlfriend. One who can be kept on a string with a few texts here and there.
It's irrational. Mostly. I think there are probably people who do that. But I don't think Castle is one of them, honestly I don't think Dag was, either. They are both just dudes who occasionally do fun things with their wives. So I am trying to just sit with the anxious feelings and remind myself that very few people (outside of high school kids and my batshit crazy evil relatives, anyway) spend much of their time conspiring and laughing behind others' backs.
