She did it

I read your past posts, sounds like you’ve both cheated on each other (if this is the same woman). If you want someone to really value being with you, then don’t cheat on them in the first place. If they feel that they can trust that you won’t leave them for someone else, *they* will be less likely to leave you for someone else.

Sounds like it’s case closed with this girl. Try to be more mature with your next girlfriend. Treat her like she’s special, don’t hang out with or hit on other women, and if she really likes you too, she won’t hit on or hang out with other men.

“Closely befriending” other people you find attractive: it’s a choice. If you’re smart, you won’t let it happen when you want to be in an exclusive relationship with someone. (A lesson I myself learned.)
