This guy

I met this guy six months ago, and almost immediately I liked him so so much. He's two years older than me, he's already met my dad and older brother, and has already gained their approval. We met at our summer job, and were automatically very good friends. Everyone at work said that he liked me, because he would go out of his way to talk to me, and was always so sweet. The only thing was that he had a girlfriend. At the beginning of September, he sought me out at work and told me that he and his girlfriend broke up. I was so happy that I might finally have a chance with him. Well our summer jobs ended, and nothing happened except that we exchanged numbers and followed each other on instagram. A few weeks ago he added me on snapchat. This past Friday, our schools played each other in football and after the game we just stood and talked for almost an hour. Saturday he started snapchatting me, and we talked for hours and hours. This morning he sent me a snapchat, but I got grounded from my phone before I could open it and respond to it. I got my phone back tonight, and we snapchatted a few times. Then he just stopped answering. Then, on his 'story' he put a picture of himself saying "I <3 my bf Jennifer Gabrielle Johnson". That's his exgirlfriends name. It literally broke my heart. I really genuinely like this guy (Tyson) an i really thought we were on the verge of a relationship. I know it sound petty and immature, but I feel so happy with him. Every other guy that I develop a crush on, i find something wrong with. Like "I like him but..." I can't find that 'but' with Tyson. I just genuinely like him. I can't do anything if he doesn't like me, I accept that. If he wants to be with her, he'll be with her. I just want to know how I can get rid of these feelings for him. How do I get over him? How can I make myself feel better about this?

u should leave him alone before u got hurt this guy his not over his ex he still hurting and loving her...he might with u to get over his stress and u might be his rebound gal and they might fix things with his ex and where would that leave u and to post her ex name his showing u the sign that his still dig his ex and does not care how will u feel
