Did I lost my cancer male forever?

Hi I am a female Libra and I need help. I fell head over heels for a cancer male. I met him a week before I was about to move. We spent a week together before I left. It was wonderful. He was
everything I wanted in a man. He said he wanted to be "special" he didn't want to be another guy in my life. I was looking for a fling but he was really special!
Two months later, I joined him for a
road trip across the country because he was moving. I went out of my way to spend time with him. I stayed up for two days straight to get my papers finished for midterms in order to leave early. He told me about a "friend" of his whom he met before he left. He showed me her picture and it made me feel really insecure.
He was really moody and difficult. We still got along pretty well. I confessed to sleeping with my ex-bf's
friend to get back at him while we were together. I also confessed
that I still communicated with my ex while the cancer male and I
had met. He seemed upset and withdrawn. He also blatantly
confessed to having 'female' friends. He said he would call me but has not.
Should I just give up? Did I totally blow it? Please help me!
