Most Helpful Guy
He might have not been sure the day you met if he was interested or not. That can take time to figure out. Avoidance behavior is really cruddy thing to do to someone, but it is a very common selfish behavior that people have. They want to avoid the guilt and confrontation of a situation they don't want to be in. He is probably trying to justify the situation by saying to himself that it would be mean to tell you that he doesn't like you, so he doesn't and he just hopes the issue will go away.
It is sad that people do that to others and can't be open. I hope you find what you are looking for.

You have to learn to separate love and sex. One day you will meet a man that is everything to you. But, I truly don't believe this guy is him. That's why he is acting out like he is. Next time, put in your mind that you will not fall in love. You are having relations because you have needs. Put yourself in control of your sex life. Date a couple of guys you may not really want a long term relationship with. And, be honest with them and say that you are just temporary, but you can be friends if they ever need to talk. You never know, if you become friends with these guys and learn more about men you may find the right one. Happy dating.
