Thank you TeaK and Anita. these answers are greatly contributions to my decision.

He believes that if he is too nice to a girl, the girl will start to lose respect/ interest on him. He said this because he has experienced from seeing his friends (got cheated on, dumped,etc… just because they’re nice guys). I told him that there will be someone out there who will appreciate the person’s kindness, not all will lose that respect or take advantage of the kindness he offers. But I know, in his mind, he thinks being nice is wrong thing to do.

It seems whatever he sets to believe in, he will keep believing in it and says it’s reality.

TeaK, I get angry and upset when we argue over small things like this. it doesn’t go anywhere, and there are just so much more important things out there to be worried. But I know I cannot change his thinking, and I don’t have that power to do it, and I know I won’t. Sometimes, I just don’t know whether it’s my fault, or things I say, to make him feel this way. I’ve been trying to assure him that I love him, and I guess it isn’t enough for him to let go of his insecurity.
