Is it normal to not want a guy that sleeps around?

I really liked this guy, and I thought that he liked me also. He used to chase me across town and told everybody about me. My problem was that he sleeps around. The last straw for me was on Christmas when I went on his Facebook and I saw that he posted pictures of some girl with his mom and entire family. He didn’t say that they were dating but it was obvious that they were. I was mad over the fact that he already had a girl around his mom, and posted pictures with her? It was rubbed me the wrong way so I moved on. My friends told me that I’m wrong because he wasn’t my bf. They tell me that he is really into for chasing me so long. Long story short is that he’s not with the girl anymore, but I still can’t get over it because I think that he plays games intentionally just to be spiteful. It also comes across that he has a sex addiction. One minute he’s in love and wants to ask me out than the next he’s banging some clown. Even when I first met him he always used to cry to his coworkers about me like a girl, than he would sleep with some of them. He’s a weirdo who obsessed with me but never wanted to do right by me. I feel like him bringing that girl home was “a joke” but I’m tired of his jokes. Nothihg is cute or funny to me. I know that he’s not my boyfriend but in the beginning it’s always fireworks but when it’s not lol that’s a red flag. He’s a crybaby dirty dog. There’s is a part of me that does want him badly but there’s another part of me that doesn’t. I even moved away just to not see him anymore since he used to always invade my personal space with his toxicity. He used to bring his friends around me just so they could have something to talk about. They all watched me like a dog. I was “his girl” in his head when his actions said other wise. Please help?
