This isn't intended to be a pity post but I'm really struggling to understand why I continue to feel this way and how I can move past it...
To cut a long story short, I was married to my ex husband for 7 years (together 12) and we have a DD who is now 10. We divorced 4 years ago now when DD was 6. The last 2 years into our marriage I changed completely as a person due to significant weight loss, and I was going out with friends a lot, gym, events that kind of thing as I felt like I had a new lease of life. My ex wanted the family life but I was just blindsided by this new feeling at the time and looking back now I realise how appallingly I treated him...He told me he'd had enough of my behaviour (at this point I was just never home) and he didn't feel like I wanted to be in the marriage anyway and he left. He continued to see DD obviously.
At the time I thought that was too what I wanted. Ex moved on quickly and has been with new partner for 3.5 years now and he seems to have an amazing life. I have had a few partners but both haven't worked out (cheating, just generally treated me poorly) and now I'm beginning to regret my actions all those years ago. I feel like those 'party' days, albeit came later on in my life, are past me and I now want what my ex used to tell me he wanted for our life. I know this is such a cliché but it's true. I accepted my fate but recently over the past few months I have a strong desire to message my ex and tell him all this, apologise and just see what he says, but I know it's probably too late.
My friends tell me that it's not my ex I want but a partner that can bring happiness to my life again but honestly after dating I realise what a catch he actually was. They tell me he should have been supporting me after weight loss and that he was just jealous that I had made new friends and was experiencing life without him....I really have no idea what to think about it anymore tbh.
What are people's thoughts on this please? Do I tell him?
