Having scanned the thread to be sure that the responses have been more or less consistent (and probably correct), I’d like to ask about something you posted:
*”Here's a few examples of what he says to me:
I'm miserable and have a face like a smacked arse 24/7.”*
Are you and do you?
”None of our friends and family like me.”
Sweeping statements like this tend to be projection but, assuming the two of you interact with his family and friends, does he seem awkward or embarrassed? Could there be any truth to the statement?
”He insults my friends and family, claiming he has no interest in spending time with my friends and my family are a 'sht family'.”*
I’ve been guilty of saying this in past relationships, when my then partner takes every disagreement we have, or personal bit of business (financial, emotional, whatever) and shares it with their family and friends. It made spending time with them like how she would feel if I described the consistency of her period discharge yesterday to MY friends over dinner (didn’t happen, just describing the atmosphere) and made me less interested in going to visit any of them. It felt like lines were drawn. Has this been the case with you?
”Whenever I get my hair/nails done or decide to dress up nicely, he tells me that I'm doing it for the attention of other men.
He accuses me of texting other men and when I've asked for some breathing space before, he's accused me of 'running away to another man's house'.”
Again, this can often be projection, and some people are just insecure, but are you doing any of this, or have you in the past?
”He's told me that I have a pathetic, sad, boring life.”
Well, it’s his life too. This sounds like pure degradation, but does he have interests that he’s shared with you that you’ve been meh about?
”I do all the night duties with DS, and he has laughed at how tired I've been.”
Based on your list, I’ll assume this is a pointing and laughing sort of thing rather than an ironically chagrined laugh of commiseration.
As you said in your OP, the stress of having a child has put pressure on a set of already existing cracks in your relationship. I’m not looking to make you feel guilty or second guess yourself with my questions, I’m just taking it as given that he wasn’t an asshat from the start and so am wondering if any of what he’s saying might have a discernible cause.
Take care of yourself, and see to the needs of your child. If you do move to your parent’s, try to maintain the good relationship you seem to have with his parents, for the long term sake of your child.
Good luck.
