Did I lose 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 the ex while we were together. I also confessed
that I still communicated with my ex during the time 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 He seemed upset and withdrawn.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! I haven't heard from him since my trip but I did meet his mom and dad. He wanted me to.

Why do those in love play games? This is the end result.
You probably did lose him, I am a cancer myself - and if things get too emotionally stressful or I lose trust in someone...it's over!

I thought you guys were good at expressing your emotions. He just got into his shell and never came out. When he did come out - I took things personally because he was so moody. How can I get him back?
