You know, I think if my husband (I'm using him as an example because I'm married, but this would go for boyfriend also) ever asked me to get out of our bed because he wanted his kid to sleep in it, I'd get out to the nearest motel and make plans to call the movers. But maybe I wouldn't be that harsh. It's just that I can't imagine him even asking this. We get crowded out sometimes by our son wandering in and climbing into bed with us in the middle of the night, but it never translates into him asking me to leave. Both he and I have had times when we just got up and went into the guest room so we could sleep, if our son had ensconced himself into our bed, but never would one of us ask the other to get out because the son needed the space. Usually one of us just wakes up the kid and walk him back to his room.
How did that conversation ever even happen? I guess I am asking if he really did directly ask you to get out of your bed so the kids could be in it. Or if you just decided to do this. If he didn't ask you to get out, but you just decided things were too crowded and got out, that is a really different issue than if he asked you to get out.
Sounds like too that you get the raw end of the deal. Why isn't your man contributing more to finances? I'd not settle for a guy I flip the bill for. That's just me but he doesn't sound like the best catch.
I think to be honest, it's hard to be with someone with kids. If there are no other beds as in he's not getting his kids a room of their own or beds, then they should get the bed when he sees them. They come first. That's hard but how I see it as a parent. So, would a solution be to get a place where they have their own room and beds? Then you have your room the two of you share and they have theirs. Or at the very least, you have a second room with a bed for yourself if he feels he wants to be with them when they visit. (and this sounds like visits more than shared equal custody?).
I never slept with my kids. But lots of parents do. And your boyfriend sounds like he is trying to attach to his kids when he does have them. Sorry, this sounds like a hard situation!
It sounds like he feels bad for not being with the kids and is trying to compensate for this by being warm and close when they are there. Too bad it means you can't even be in a bed. I guess I would talk this out with him with a counselor.
