People aren't trash. You haven't given many details, so it is hard to know why this keeps happening, but it likely is that there is a mismatch between your values and the values of the women you choose to date. Not everyone looks; I didn't when I was married; it never even occurred to me. When you say you treated the women well, in what way? If you gave them lots of material things, maybe you were really connecting with women who valued gifts over emotional fidelity? Next time, try taking the relationship very slowly and if you were giving gifts, hold off until you see what the woman's character is like. And listen closely when she tells you why her last relationship failed. You want a woman who appreciates the sentiment behind a bouquet of flowers, not a woman who requires a fancy cell phone and a sports car to allow herself to be your girlfriend.
