What the hell do I do?

I’m having some trouble I was seeing a guy named Sean. He had hung out with the same group of friends I do and that’s how we met. He gave me his number and we started talking. We got a long fantastic! It got to the point where he had me staying at his house almost every night or at least every other night give or take. Well when I asked what exactly this was he said he didn’t want a relationship because he leaves for work in the fall and won’t be here and he also will be traveling for bronc riding a lot. I had kind of come to terms with that for a bit and then we had decided to just be friends. So we hung out with our group of friends and didn’t do to much talking but we weren’t really ignoring each other either. He would kinda poke my side or hug me then and there. I didn’t put to much thought into it. he asked for a ride back to his place because he had to take the car back to his friend and I said okay. So we got in my car and he asked to play a song so I handed him my phone and he puts on a love song and holds my hand. At this point I’m so lost because we had agreed on being friends. But I didn’t say anything and went with it while slightly freAking out in my head. We got back to his place and I ended up staying the night. Well we ended up going to a rodeo with our group of friends and we went to a big dance and he’s huge into dancing and usually asks me to dance. Well he didn’t but his friend did and had told me that Sean kept watching me as I danced with all these other people. I started to get a little flustered but ignored it and went and danced with a old friend I haven’t seen in ages. After that he drug me to the dance floor. No asking just took my hand and basically flung me out there. I had been getting really upset about it also because he was grabbing another younger girls waist and would dance with her. At the end of the dance I had asked again if he saw us going anywhere and he said “no not now. “ and I said “I’m not talking about right now. I’m talking about ever” he had responded with “I don’t know” I told him that he couldn’t play with my head like that and if we were just going to be friends it needed to stay at friends because I had feelings and that wasn’t fair to lead me on. He agreed and I left crying. We hangout with the exact same crowd so it is incredibly hard to dodge him. He won’t answer my calls and he kinda seems to not even care to talk to me and I know I shouldn’t care. But I hear about these other girls and see him with other girls I get actually really upset. I always think maybe if I stayed around he would change his mind but I feel as I know that I’m just making excuses for him. I do try to go put my heart into stuff I like and have a good time but still find myself looking at his pictures or trying to impress him when he’s around. I’m really hurt and I have no idea what to do... he won’t even talk to me if it’s just him and I.
