So I have been looking around for some guidance to this problem for a while and have searched these message boards a lot but haven’t really found what I am looking for. I am sure this is a tiresome subject so I apologize for that. Also I am not trying to start a morality issue here, basically it is a long story that no one will probably care about. This girl and I have had thing for a couple of weeks, we both like each other but haven’t done anything sexual, because she has a boyfriend (they have been together a year and a half). She has admitted to me that they have been having problems. It is a long distance relationship, he constantly hangs around other girls, he is very jealous, he has cheated on her before, he is into weird sex stuff which she doesn’t like, he doesn't satisfy her sexually, and he ignores her. Her biggest complaint is him ignoring her at times. I have looking into using a boyfriend destroyer tactic by Tyler Durden. It says to try and make the guy seem insecure, which I have done by saying things like “he is unsure how to act around you because you aren’t what he is used to getting. He can talk easier to other girls because they are more what he knows he should be able to get, not a girl of your caliber. He does appreciate you because he knows you are the best he can ever get. He is afraid you will leave him, it isn’t his fault. ” At times she will believe this or start to jump to her own conclusions about how bad a boyfriend he is, but in the end it always comes back to “no, he loves me, that isn’t like him, you’re wrong.” It has only been a couple of weeks but there really seems like no progress at all. I have spend time with this other girl (who I don’t really want to get involved with cause she is leaving the country in a month) which makes her jealous, she constantly tells me that I should stay single. The worst part is that I don’t get to spend much time with her because her boyfriend doesn’t trust her around me.
