My boyfriend is cheating on me and is a sociopath but the sex is so good?

[Shelby]

I just found out that my boyfriend, whom I've been dating for 5 months now, is cheating on me. He's so sweet and perfect and charming half the time and the other half he's angry at me for no reason and completely cruel. Like legit CRUEL. I've looked up the symptoms of a sociopath and he fits EVERY description. But ..our sex is SO AMAZING. I have NEVER had better sex. I swear it can't get better. Now I know it's completely illogical that I'm staying with him because he's obviously a sociopath and treats me like complete shit.. if I were to begin to describe all the ways... it would be far too long... which is sad. I've been away for 2 months In Sweden and I found out he's cheating on me while I was here.. I go home tomorrow... The entire time I was here.. I was COMPLETELY faithful despite the MANY temptations... and I have been greatly anticipating my return .. because of the sex. I am 2 months sex deprived and now... 2 days before returning, I find out he's been cheating on me. Initially when I found out, I sobbed for about 2 days straight. I want to break up with him as soon as I get back but I REALLY DONT WANT TO BECAUSE I WANT TO HAVE SEX WITH HIM AND I FEEL LIKE IM INLOVE WITH HIM. this is fucking awful. obviously the answer is to break up with him... but my question would be... HOW DO I DO IT?!??! Im addicted
