I don't think people are saying that you are egotistical for not taking their advice. I think people are saying that you are egotistical and displaying a high degree of narcisissm for thinking that a guy who you don't know and who doesn't know you and may not be actually concerned with your existence if he does, is trying to prevent you from going out with his ex girlfriend. Who, by the way you haven't asked out yet. You have based this on a series of photos posted on facebook. In these photo's you have inferred from this guy's body language or something that he is possessive, potentially violent, and for some reason threatened by you. The issue doesn't have any basis in fact, it's a fiction you have concoted in your mind. I think quite a few people have provided solid advice regarding how to respond to this situation despite there not actually being a situation, but you've rejected that advice. I'm not sure what you want from the rest of us?
