This is a good question! I've only been in one relationship in my life and the one I was in it ended because he tried to rape me. That was in 2009. Ever since then I help my friends out with their problems and I'm told I give great advice. The last time I had feelings for a guy my best friend promptly dated him with full knowledge that I did have feelings for him. I'm a full-time student and work part time cashiering and deal with the public constantly, I'm always worrying about my future and I don't concern myself often with free time when I know I should. I'm stubborn, independent, and I'm a hard worker. Many of my friends try to set me up with guys and it never works out because there is always a major flaw with them, (drug addict, free-loader, or just zero personality). So yeah, I feel like I deserve some bit of happiness.
Good question. Not in the sense of "Yeah, lets get back at them" but more like a guy is actually looking out for the best for himself. Rather than rely on society's standard that says a man chases after a woman just because...your question says "Why MUST I chase just anyone? If I'm good, then I deserve to have them prove themselves just as much as I prove myself."
