I’ll start.
We had great chemistry but different goals. She was religious and looking to marry and thought she could change me, a non-religious person who intends to remain unmarried and childless. I was up front about the lack of religion and the lack of desire for marriage. She was not up front about her intent to change me.
After two months of regular flings she told me we couldn’t see each other anymore, because she wanted someone to go to church with, it was my fault she was living a sinful life (totally), and she was cheating on me with another dude was a Christian.
I do not consider past relationships failures. Given enough time, I believe we are all able to go from “why is/was this happening to me?” to “what is/was this teaching me?”
With that said, I’ll gladly share, starting with the latest:
Divorced her after eight happy years, in 2021, because she wanted kids and I didn’t. Having kids was one of her dreams and I didn’t think it fair to keep her waiting for me to have a change of heart on the matter. Also, she called me “stupid” whenever I intervened in quarrels, brawls, threats or other antisocial behavior on the streets. Lastly, she told me once, when I opened up about my clinical depression, that I probably have to live alone the rest of my life.
Broke up with her about ten years ago, after dating for one year, because she couldn’t take having a long distance relationship. In addition, she had apparently fallen for somebody else.
Broke up with her over 15 years ago, because she couldn’t wait while I sought medical care for my erectile dysfunction. She called me names too. Took me 15 years after that to realize that my dick was causing gender dysphoria, which in turn made me unable to fuck “like a man”.
My first love, over 20 years ago, I broke up with after four years of her cheating on me with my best friend. For some stupid reason, I forgave that sorry excuse of a human being every single time, destroying my self-esteem for life in the process.
