It's hard to know what is the specific trigger that made your partner to devalue you, they will rarely tell you because most of the time they don't even know themselves, it can also very well be an accumulation of several things. These things would show her you were not the person she idealized and she would start having trust issues because of that (this guy is not who I thought he was so he lied to me about him being perfect, I can't trust him anymore).
If it can be of any relief, know that this would have happened eventually, even if you had been the best boyfriend in the world and to be honest with you, better sooner than later.
Thanks man.
Oh i remember now. It was about the issue with how many women i slept with in the past. Thats what she was crying about. She had told me early in the relationship and even during mere friendship that this stuff really bothers her and will be an issue once her feelings became serious.
Freaking hilarious how something of the past can be the obstacle of the future. Much like setting down a landmine behind you then walking backward into it.
This woman was near genius lvl IQ too. A savant at her high paying job. The irony...
