Actually, thinking about it this does remind me of a very close friend of mine who married a bloke from a far less happy and wholesome background, who could be really sulky and kind of resented her parents, despite them being really lovely people.
I'm still not entirely sure what she saw in him but still. They stayed together for a long time, then got married, then they had two children, and they were living near her folks as his weren't really bothered, and her mum and dad helped out a lot.
When the children were 5 and 2, she got ill, and she died within a year, leaving her husband and children with the big house they had bought.
Obviously her parents were in bits and wanted to keep on seeing the children but her husband fell out with them as he thought they had interfered too much when she was ill, and after a couple of years he sold the house and moved away.
Losing her was awful; now they have pretty much lost touch with her kids, too.
I hope this doesn't sound overdramatic, and obviously it's very unlikely you will be taken from your family and so on but please do consider the bigger picture before having children with him. He sounds immature and a bit of a jerk and if he doesn't get on with your folks, it's not going to be easy or happy for anyone (as he will make sure it isn't)
I sense an element of jealousy and sabotage in this situation.
You have a lovely happy family; you are right, he is spoling it. And he knows he is, too.
Time to stand up for your folks I think. And consider your future as well.
