My boyfriend left his facebook logged on at my house, so being the awesome girlfriend that I am, I read his messages. I know, I know. Well he had written some pretty illicit messages to other women about oral sex and other things of that nature. When confronted about the situation, after hours of fighting, talking, and crying, he confesses to me that he is a sex addict. Swears up and down that he has never cheated, just talks to other women on facebook.

We are both recovering drug addicts with multiple years clean, but this is the first I've heard about his sex addiction. I know nothing about sex addiction, so I am coming here looking for help. Is this something that sex addicts generally do? Go trolling facebook looking for other women to talk to? Do I believe that he just talks to women, and doesn't cheat? I know a great deal about drug addiction and nothing about sex addiction. I love him, and don't want to end the relationship if he is being honest with me, but how do I know?

Thanks.
