It's like he wants to carry on like nothing has happened.
You've got it in one. He wants you in your place and him getting his leg over with someone else.
He has done lots of superficial things like flowers and being more willing to pick the kids up
Pah, that's the easy stuff.
If I stand up for myself he gets cross and threatens to cut off any money and get rid of my car (which is in his name)
He wants you back in your place - that's why he's getting angry. He wants you to keep relying on you, hence the money and car. HE'S CONTROLLING YOU.
He blames a lot of it on me being tied up in looking after the kids and he said he felt lonely
Classic blame shifting. "Wahhhhh, it's not MY fault" Fucking man child.
Doesn't seem to care how I have felt
He doesn't.
He is v cross that I have confided in friends and he says he is uncomfortable going out in our village as everyone knows
That's because his idea of himself and what he thinks people think about him are more important to him than you are. You are ruining HIS image and potential other women and useful people.
He's showing classic narc signs. He's trying to control you and the situation so he ALWAYS has the best advantage. EVERYTHING he does or says will be about getting YOU back in your place and HIM being in control of everything.
You've got a chance to run, take it. TAKE IT NOW.
