Married about 12 years, 2 dc- one has ASD. It has never been an easy marriage and I have thought of leaving a lot over the years. Lots of nasty things said by him that could be considered emotional abuse. About a year ago I told him it was over and I wanted to leave. He was (surprisingly to me) devastated. He asked me to consider counselling, and I agreed. We did couples counselling for over 6 months, and it did make things better.
I was able to talk about the things that he's said that had hurt me so much, effected my self confidence etc. He was clearly upset and sorry for this and has genuinely made great efforts to change things. He was also assessed for ASD, but although there were traits there wasn't enough evidence from his childhood. But I would say he so similar to our dc with ASD. There was also mention of him being emotionally neglected as a child and the impact this has had on him.
So generally things are much better than they were, we communicate better, he pulls his weight, we feel more like a team in dealing with the dc.
However, I'm not sure its enough. I also had psychotherapy last year and one of the things cemented by this was my realising why I married DH. I had a string of relationships and some abusive ones, where I was eventually cast aside as not suitable for marriage/long term commitment. When I met DH I was in a very unstable place and he was very full on, very romantic and also very stable. He proposed within months, we lived together after 2 months and were married within 2 years, had dc1 in the first year of marriage.
I don't think I ever loved him really, we are very different. I loved the idea of what he was offering. So although things are better, I can recapture the love that wasn't ever there.
I know that if I had the money to buy him out of our house, then I would absolutely do that and end it. But I don't and he doesn't, so we would have to sell the house, rent (I couldn't afford a mortgage) etc.
What I know is that no matter how much better it is now, I still regret marrying him, I think I will always regret marrying him.
