Can I change how I look?

Your looks don't suck, it's your attitude. There is no way you will be able to change your height and build...I mean, that's the way God made you. You are who you are. That's like a 5' 2" plump girl asking to be a 5' 9" supermodel. It's just not realistic. You have to work with what you have. What's wrong with a woman viewing you as a protector? You have obviously have had dates and what not, but you seem to find something wrong with her attitude towards. Geez. I honestly think you are a good looking guy. But your attitude is shi***. Looks only go so far. I used to date a gorgeous man. His attitude was horrible and we broke up after 3 months. Seriously,, you need to work on the self-esteem. Maybe talk to a counselor. I realize this is viewed as taboo, but sometimes we need to empty out our guts to someone. GOod luck.
