Why is a great girl like you still single? Never underestimate the power of love! He is a manipulative liar and con-artist.
I know that is what he says, but is that what he is showing you? Just because a man is with you and he is sleeping with a man does not mean that he loves her.
In comparison to them, he's cool and relaxed.
If someone comes along with more cars and more houses and more money, would you just consider yourself inferior to them and just think, oh, he´ll cheat with this person, she is just a better catch? She controls the mood in the home and the happiness of his kids.
