"Anyway he moved in to my house pretty quick and I had a few reservations but kept dismissing them. ... and almost but not quite calling me a gold digger for marrying an older guy. ... and then started ranting how he's sick of women like me (a couple of his ex girlfriends were childless) who chose not to have DC thinking they're better than every one else."
This is what you've said about him, I've just dropped out some of the other details. Side by side, it makes his attitude to women pretty fucking clear. He despises us. He thinks we are only good for having men's children, women who don't are uppity bitches. When he says "thinking they're better than every one else" I suspect what he really means is "thinking they're better than every other woman and equal to men".
And yes, he does think you're a gold digger, there's no 'almost' about it. Which is why he has no qualms about cocklodging you (the male equivalent to gold digging) because he sees anything you own as really belonging to another man, your first husband, and so he's happy to annexe it to his own use. What reservations did you have, the ones you kept dismissing?
"I know I won't LTB as I said, 90% of the time all's fine but I need him to just stop being a twat - again AIBU?"
If your health was 90% fine but you were in pain 10% of the time, would you dismiss the idea of going to the doctor to find out what was causing the pain and having it treated? Because that's how you're treating your marriage. It's a pretty low bar you're setting. And what if that 90% drops to 80%? 70%? 60%? What's your threshold of how much open contempt you're willing to accept?
He won't stop being a twat - this is who he is. The 'honeymoon period' where people can pretend to be better/nicer etc. than they really are is over, you are now seeing the real him. Even if he managed to not say this shit, he'd still be thinking it. Is that acceptable to you - covert contempt rather than open contempt?
I really think you need to have a good long think about those reservations you had a the start. I'd bet money those reservations were valid then, and still are. And also, have a think about why you're willing to put up with this. Maybe your first divorce was so bruising you don't think you could face another one, but it could just as easily be easier second time around.
