Am I the problem?

@Sarah 💛 not really, no. We do things on the weekends sometimes with the kids but a lot of the time he will just be really moody and sit there huffing, swearing and moaning saying he doesn't wanna do anything and is in a mood etc. But it's nearly every weekend.

I've asked if he wants the family life and also if he wants to be together and he either says obviously you idiot or obviously don't be stupid for fuck sake. They're his actual words any time I ask anything.

I just don't know why he doesn't ever want to do anything when I'm there too. Makes me feel like a problem and almost like I'm in the way. Xx

I would have told him to do one ages ago, there's no excuse to speak like that. Get rid of him then run to freedom

You dont deserve to be spoken to like that, you're not an idiot - have you asked him why he thinks it's ok to call you names?
Maybe tell him that it doesnt seem that he wants to be with you - and then list your reasons why.
You could advise him that your thoughts are not stupid and the way he is conducting himself and treating you is not healthy and is not contributing to a satisfactory relationship.
