First of all, anybody that feels the need to take revenge, to punish another person for their own selfish reason is a loser because he sacrifices his integrity for the satisfaction of sharing his pain. And it affects your self image by reinforcing your belief that you're really a bad person. But anyway, if some girl isn't interested in dating you, and you're SUCH a great catch, isn't that her problem? And if you're not that great, well can you blame her for moving on?

Here's an example from a couple of years ago: I had one boyfriend who went berserk on me and my whole family after I had to get a restraining order to make him leave my apartment. And even then, I had to pay off my lease and move out because he continued stalking me. On top of that, he stole an obscene amount of money from me (I was naive enough to keep cash around him) and basically destroyed my life for a solid year afterward. Even now, I don't think I'll ever be the same.
And he did it because he "loved" me. Maybe I wouldn't have had to dump him if he hadn't acted psycho, but did he really think that making me suffer would inspire me to come running back to him? Yeah right. It only reminds me what a loser he is and makes me more grateful I didn't stay with him.

So guys, if this is you, NO WONDER girls don't want to date you.
Unless you spend money on them. Ha ha ha.. ROFLMAO
