I have struggled with Oneitus on and off for about 5 months now. The common advice I got on here was lift and keep fucking girls which I am doing, but I can't seem to get over my hatred about the situation.

The situation in short: While I was dating my LTR my best friend had clear interest in her. He would talk shit behind my back to her and mention how he would be a good bf and get along better with her family, shit like that trying to ease his way in. Eventually I broke up with her and sure enough they start dating even though she said she would never have any interest in him (lol). Basically, I'm not sure if it is Oneitus or me just hating both of them for the situation. I am having a tough time moving on when I lost my two best friends and am having difficulty creating good male and female relationships since. My loneliness only makes matters worse and makes me miss her more even though I know I needed to end the relationship.

I fell that if she was with any other guy I wouldn't care in the slightest. Looking for thoughts/reality check from you guys. Thanks.
