He's mad because some chick he had a crush on slept with a friend of his. Your fault pal, you should have made your move sooner. The saddest part though, I don't think she would've been interested in you in the first place. Because guys that feel, act, and think the way you do are not attractive to women, in fact, you're the exact kind of person most women should and will try to avoid.
At least, thank God, you'll never breed. That way, once you're gone and buried, the world won't have to deal with the likes of you ever agin.
