"Why would he insist on contacting me when I asked him not to? Was it really to Bipolar or not? Why is he so depressed/sad if this is what he wanted"

My son is bipolar. It seems as though he is on a roller-coaster all of the time. He says one thing one day and the reverse the next. My guess is that you are a very kind person with a big heart. That is how people describe me. And we get hurt by the people we care about because of it.

Use those good qualities of yourself and move forward. If you want to try to be a friend to your ex, please just use caution and please take care of yourself. There is probably a wonderful person buried deep inside of him, but he isn't ready to commit to a serious relationship because he isn't yet comfortable with himself. I saw this happen with my son and a woman who was in love with him.
