AITA for not telling my son I had his girlfriend removed from his wedding?

Back in the 70s, I fell in love with a woman and was willing to spend the rest of my life with her. When I introduced her to my parents, they absolutely despised her because she was poor and they believed she was only using me for my money. I couldn't tolerate their distrust of my choice in a partner and decided to cut them out of my life.<br><br>I started trying to find a middle ground for our parents and children when about 9 years ago my son's girlfriend left him for his best friend. He was absolutely devastated and only afterwards did he tell me that I had been right, their relationship was mean and toxic and he had only kept her around because he felt sorry for her and wanted to provide for her. He had a great time at university, made life long friends and enjoyed his time, but his girlfriend constantly belittled him in private, made him do chores and in one instance which I can't condone she burned his books he was reading for fun.<br><br>When he announced he was getting married, I met his fiance at his wedding planning. She was very kind and polite and if she wanted to get married then I would have had no qualms about paying for it, what really was the problem was that she didn't actually want to get married. And she told me she was just around for the money and that she was "using him". I took extreme exception to this and she even agreed to break up with him in exchange for me paying for a luxurious holiday.<br><br>She called a few months later and said she couldn't cope with the guilt, she had been feeling soft about my son long before he started dating her. She said she wanted to be with him but didn't want to end up like me. I said she could break up with him and I would pay for her education instead. She agreed and I thought that was the end of it.<br><br>One of her friends had been going through a similar thing and I met up with her a few times, we didn't necessarily want to break up the men who were dating them. We agreed that our children should meet and we'd go on a double date, we could have a lovely time together while they went out.<br><br>I met her once and I knew straight away I liked her, she was smart funny and a very kind person, it's no wonder my son fancied her. I soon felt the same way as my children were my biggest concern, and to be honest I felt a little guilt for outsourcing the problem when I could have just raised a better person. I decided that I had to be honest and I told her that her daughter was my son's ex. I thought that would be the last time I saw her but she was glad I was honest and thought that it would be fun to go on a double date with our children.<br><br>It took a few message exchanges but our children agreed to meet and go out with their parents at the same time I asked them to meet at the restaurant if that was Ok with her, it would be a little less awkward for them that way. She agreed and I told her I would pick her up at 7.30. <br><br>We turned up and from what I could tell our kids had a great time together, at one point I think they even shared a kiss. They haven't since spoken but I'm glad they became reacquainted. My wife and I have been together for 3 years now and she's the love of my life, I'm in my 60s now and I've always wanted someone else.<br><br>I told my son a few weeks ago and he was absolutely livid, I've never seen him act like that before. He said I have no right to interfere with his life and he was starting to understand why I didn't get involved all those years ago, because I was a manipulative sicko. He said he was going to go back through his whole life and start questioning if any of it was real.<br><br>I told him to stop being dramatic, I just wanted to find someone to date and who cares if it was his girlfriends mother? I sort of regret that now.
