[17/f] My boyfriend [17/m] We've been going out for 2 years.

Basically, for the past month him and I have been in on-going fights. Last year, end of August, I was apprehended by social services ( a different story ) and he is a manwhore. He texts every girl that he knows and he even knows they're flirting with him and stuff so he stays, which really bugs me. You are not allowed cell phones when your apprehended because you could talk to your parents, so I called him every day after school and he said can't talk hanging out with people. I could hear girls giggles in the background. This was 2 weeks after I was apprehended and he tells me he's hanging out with his ex-gf. Totally broke my heart. He continued to do this everyday after school. I saw him every week, so I had a talk with him. He said to me he wouldn't do it again. He did. Whatever I give up, so then I invite him to a haunted house thing which he ditches me last minute for soccer. I said that's enough, so we took a break. The next day we broke up and we did not speak till Halloween, which is when I was given back to my parents.

A week later I went to highschool back at home and he goes there too. We hung out at lunch and he showed me around. A week later ( We both still have feelings for each other ) we got back together. Now, after being happy until around the start of June, fights have started again even more intense before. He calls me names all the time ugly, whore, slut, and now bitch everyday. The only names I have called him is stupid, ass hole, and dick. He's been the most irritable person lately he says it's over when we get into a fight and changes Face Book relationship to complicated. I said to him that I think he is doing something behind my back. Another girl that loves my boyfriend to pieces tells me that they were talking (in a in your face attitude) and I confront him. Apparently it was just one thing, but I checked his Facebook and he is adding random chicks, deleting messages, and notifications. He still won't tell me why. He also says the most hurtful things he said that his whole family thinks I'm a little bitch and that I should go cut myself deep and die. But, I really love him and I do everything for him, I can't hang out with any friends both gender or text and he always says sorry, that he loves me, and wants a future with me after the fight. This is my first real relationship and I need advice!

tl;dr Boyfriend of 2 years is being secretive and hurtful on a daily basis.
