My On And Off Ex Told me to leave him alone.

I dated my ex on and off since August 2013. We got together a month after him and his ex broke up. The next month he broke up with me to get with her. Then the next day he came back to me. We had also made love for the first time. I immediately fell in love with this man. Yet, his ex stayed around. They would call each other and send each other sexy messages. He told me he has never slept with her because she is a Virgin and she wanted to be married. He told me he didn't want to do it with her for that reason. We dated on and off again for 3 more years because he refused to be with me because of how clingy I was. I was scared he would leave me after I threated his ex, told her to stay away. She wouldnt. He told her he was sorry he was making her feel like he didn't love her. He then told me we couldn't be together because he was in love with two people. Since I'm bisexual, I didn't care if we all got married. She doesn't want that. So I wanted him for myself . He told me I gave him an ultimatum. So eventually, we were about to work at the same job. He told me before I was going into start my first day , he didn't want to have anything to do with me. So I left for a couple months. I came back and he said be with him and he was not worried about his ex. But he let me have his phone and i found out...his ex dosent want him no more. So, he driving himself crazy over her...he won't let go....he told me he loves me...but he Does not want me. I know he is in love with her because he complained about her a lot. ..and he didn't care what I thought. It is hurting because he dosent go crazy over me like he does he does for his ex. He will not let go of her. I pushed him away for being a bad boyfriend over the years and now he won't answer my calls or text..he told me to see other people but I told him no , I want to wait for him...he told me he is not waiting for me....help me..please no rude comments..
