Just broke it off with the love of my life fiancé I dated for over a year and 6 months.

In the span of a week I found out she was "kissing" another guy at her work. Then I find out that she and him are "innocent joke flirting". Then it just spiraled out of control from there. First confrontation I confronted her and him, said she was dumped on the spot if she didn't come clean and stop seeing him. She "came clean" which were all half truths that they didn't even kiss and she just innocently flirted. Said she would stop talking to the other guy I thought things would look up. It took until her friend called me and told me that my ex was making out with the other guy and then sending me this exchange she had that I finally had enough of trying to be mature and value our relationship. Her friend is in green, my ex is in blue. link to the exchange.

Just broke it off with her tonight, as she was coming back from a date with the new guy. Funny thing is. the new guy is a low testosterone punk
