Hi OP, I could have written your post.
When I met ex Dh he had a small property portfolio with his brother and dad. All the houses were put purposely in to ex name so mil or now ex sil couldn't get their hands on them in the event of a divorce. Apparently ex said he'd never get married.
Fast forward to meeting me. A year in we had an unplanned pregnancy and started our family off. We discussed marriage many times and he felt it was something he had to come to "on his steam'. I talked about going on the deeds of the house we were living in which was flat out now as his father and brother owned a share.
At this time I gave up work to do the child care as ex wanted to start his own business up. That was my biggest mistake although we literally couldn't afford payed childcare.
About 8 years in his DGM had been for a meal with ex and I went to meet them after. Whilst ex was playing with kids she mentioned that she had asked when we was going to get married and he told her he wasn't the marrying kind. This was said in front of his family. she told me not to worry as its only a bit of paper. I felt humiliated.
At home when every one had left I pulled him over it. I was upset and said all there things you have said on here. I felt cheated too. I had gave up a career I loved and was really good it.
He said it was a joke and that we should go get a engagement ring and plan a wedding. So we did. Much to the surprise of his DGM who actually brought it up again. Much to the surprise of his family who know were shitting themselves as I was about to have a share in their property assets.
Tbh the cracks in our relationship had started to show at this point but now way was I walking away from this with nothing. He now had a successful business and I'd had 8 years of no sleep and being a general dogs body.
The run up to the wedding was awful, the wedding was awful (huge family difficulties and arguing)
We never really recovered and we are now divorcing . But I'm glad I went through it as I'm in a much better position now than I was pre-marriage.
The thing is with men like this is why should they marry when they have it all anyway? For me is a clear sign of where they view or respect you.
If he will not make that commitment, now after all these years of commitment off you - leave and set up your own security. Because this is what its all about isn't it? Why would you be left pissing in the wind if he decides to end it.
