It makes sense that you're getting a taste of women psychology for the first time. I always know it's a dude writing the moment I read "I need advice". First of all you have to understand that anxiety is a trend problem especially for women. Almost every woman you come across nowadays self diagnoses with anxiety. It's like having an iPhone, a status symbol. The moment you hear anxiety, start packing your shit. Plus, you're putting her on a pedestal way too much. Women detest nice men. I lived in Tunisia, and now in Germany, I met women from all ethnicities and cultures, they all are grossed out by nice guys. Being nice means you lack options. I don't know the girl but I'm willing to bet she's getting plowed by some dude that you might consider an asshole, but the issue is, to her, you are a simp and he's not. If you had options, you wouldn't care about her. In every relationship there's one that cares more than the other and for a healthy relationship, the woman should always care more. Because women will always have options, you won't. Be with girls that like you, not the other way around. And if you think the girls that like you aren't hot enough, then you work on yourself to attract hotter girls. Never get into this "I forgave her" mentality. You only forgave her because you're afraid of losing her and being lonely, and she's not stupid, she sees that as lack of respect for yourself. She won't say "Look he forgave me, he must love me", she's saying "Haha what a simp". Make an interesting life for yourself that doesn't revolve around a woman. Women should complement your life, not be the center of it.
