I need some advice, my brother has been dating this plain looking chunky chick who has one child. He had lost weight (130 pounds) over the last 18 months. He is a decent looking guy, but he has very low self esteem, he cannot carry on a conversation. he has dumped this woman 5 times over the last 4 months, If we go into a club and she is there, he will start talking to her after 2 minutes. After that they are back together again. when he splits with her he tells her that they have nothing in common (except drinking,no sex). When she went to her 10 year class reunion she left him to watch her child. Recently (yesterday) she uses him as a babysitter, and he refuses to tell her NO! He doesn't call friends when he is with her, anyway----has anyone ever encountered someone who is a wimp like this? And do you have any advice? Thanks
