Should I call to let him know that I am thinking of him or not?

About a month ago, I break up with this guy that I dated for about three months. He is a wonderful man with many qualities that I don't care for (flirtation, many obsessive female friends, non religious organizer, multiple health issues, and multiple disorder). But he is gentle, loving, caring, family oriented, good kisser, and great in bed. When we break up he calls me names like "a little *****" and bad mouth about me behind my back. I'm still friends with his sister and she told me that he said things about me but she won't want to tell me. I know what kind of man he is because he had bad mouth about all the women he dated before me. Now I have hard time forgetting him because I forgive him for all that he had hurt me. I was thinking about giving him a call but not sure that is a good idea or not. I still love him and care for him very much but I also know that I won't have tolerance for his behaviors when come to his obsessive female friends and flirtation. What should I do??? any advices greatly appreciated.
