Mil drama

So me and my OH have been together for 3 years, me and his mum do not get along (screenshots below)

Anyway, about 7 months ago me & my boyfriend got into an argument and every time we do he always has a bus ticket booked to go "home" which is 200 miles away. He can't drive so him seeing baby (who's 11 months) would be extremely difficult. Because my OH said he didn't want to go home she threw out "I have six weeks to live" (she didn't. It was a lie) to which I said enough was enough. She's so desperate for him to go "home" to her, he's 27 & she sent him 200 miles away to a rehab when he was 16 & never bothered to ask him to come home. He now has 2 kids down here (I'm the mum of one, but she doesn't bother with any of them) she came down when baby was 2 weeks old for 3 days & she held baby for 10 minutes, I've sent he r pictures of him and she ignored them, she won't even say babies name - she cares that little.

Anyway, I'm fed up of living a life where my Mil's wants/needs/opinions etc are all my OH listens too, he could care less what I have to say but the sun shines out of his mums backside.

Would this annoy you?? I don't feel like I can cope in this relationship for a minute longer, I really can't put up with that for the rest of my life but my OH says its me and I'm unreasonable etc.

I've never imagined being a single mum but now I don't know what to do anymore

This was the beginning of the relationship

This was when she came down for 3 days, held the baby for 10 minutes because she was just so disinterested.

So yeah, a lot more has happened but I'd honestly be here all night. I have no one to talk to and I'm just wondering what others wod do in this situation 😭🤦‍♀️
