Really Hard Break Up, I Disgust Myself?

So my ex of 7 months (I think he's my ex, I have no idea anymore) and I broke up a few weeks ago. It hit me realllllly hard. He was really my everything, I lost my virginity to him, all I wanted and more. But things changed, so did he, and we decided to end it. The first few days I'd randomly cry throughout the day, always at night, he never left my mind. No matter who I was with, what I was doing or anything. It was a few days before graduation that this happened. Graduation night I went to this party and one of my friends who I know used to like me sophomore year was there. By the end of the night we made out. About a week later, 1 of my other friends of a few years, and his brother, and his brother's ex went to the pool. By the end of the night I made out with him. Than some friends and I went out to this party the other night, I met this really hot guy... we danced, made out, almost hooked up. My ex found out about this and he said I disgust him and called me a hoe, even though I do feel like 1 now... We broke up in the first place because he became really neglectful to me for over a month, not 1 phone call, 10 mins of texts, and he wouldn't see me. But those other guys made me feel at least somewhat wanted... even though I really got nothing out of it. I guess I stopped caring. Like guys tell you whatever you want to hear than toss you to the used junk, so I figured what does it hurt to do it to them. I was having a lot of fun but now looking at myself I'm really not content with who I am, and I don't know what to do.
