I would not get involved with this man, and I would end the relationship. A man who will not stand up for himself won't stand up for you.

I agree, the ex-wife is entitled to half of his assets after such a long marriage, though I think she's going about it in the way she is because she knows she can browbeat him. She knows she doesn't have to ask nicely.

Re the inheritance--My personal opinion--His inheritance is his unless his mother specifically stated in her will that the inheritance is meant for him and his current wife. But I'm biased. I've seen a family situation in which carefully wording a will saved a relative of mine from having to give any part of her inheritance to her husband; her parents ensured that she would inherit their money, not her (now ex) husband.
