Confused. Need help and advice

I am girl. 21 years of age. I met a guy 7 years back on a dating site and fell in love with him. I met him few times and we even got into a relationship. Then after 7 months he left. I was hurt, though I was a kiddo at that time, I really felt that I loved him. Then two years after he came back in my life and we again dated. Then again after 7 months he ditched me. Somehow I managed and went on with life. But deep within I couldn't forgive him for the pain he gave me nor could stop loving him. I always felt he used me. Then after a year or so I met his friend. I had an amusing idea of taking revenge from him and went in a relationship with his friend. He came to know about us and definitely we fought a lot. He even called up at my home and said everything to my parents and situations went berserk. I stopped talking to him and I said to myself that I don't need him. I really went strong until after a month he texted me "I'm not well. Can you call me?". I talked with him and forgave him. I was happy that he came back. Now after he ditched me the second time he went into another relationship and currently is living with that girl. On the other side we me and my ex aren't exactly friends nor lovers. I really don't know where I stand. All I want to know from you guys is how should I deal with this situation? Should I keep talking to him. Can I get him back in my life???? I really love him. Help me.........

I don't think you should keep talking to him. It seems like after you went out with his friend he only asked you for help then next thing you know got into a relationship just to get back at you. Yes. He may have been in your life way back when. But off and on relationships are never good and it seems like he hasn't changed since 7 years ago. I would move on
