I’ve tried to take lessons from bad past experiences and not do the same to someone else.
For example I had one ex girlfriend ghosted me after dating for 9 months after a minor argument. A few years later I found myself in the reverse position (wanting to break up). Even though I didn’t want to see my soon to be ex face to face (because I knew she would go ballistic) I gave her the respect of doing it anyway.
She went nuclear and it lasted for an agonizing 2 hours. Culminated with her threatening to kill herself (she didn’t do it thank God). But I left knowing I did the right thing. I let her get everything off her chest. Gave her closure. Also her behavior sadly confirmed I made the right choice.
But I find that usually women use bad past experiences with men as an excuse to screw over innocent (ish) men they meet in the future. Like they are “evening the score” by getting back at an ex by screwing over an unrelated man.
Reason I say this my experience grown women in their 30s with emotional baggage actually get worse then older men who have similar bad experiences.
