I think im inlove with my co -worker

I think I’m in love with my co-worker, but he has a girlfriend. Every time I have a problem he always comforts me. We don’t usually talk at work but we see each other outside work. We always go out late at night. Before I only see him as my brother but, one time when I was so drunk and I’m crying because of my boyfriend. He went out to meet me and comfort me. And I was shock when he kiss me that I can’t stop kissing him, he said he likes me. But he has a girlfriend and they’re in long distance relationship. One time before he left Guam he even told me to text him to meet him before he leaves because he’s going to miss me, but I haven’t text him. But one time when me and my boyfriend fight again and were in long distance relationship too, I don’t know what to do we meet again and I was so drunk that I didn't know what I did, and he is a little bit drunk he brought me to his place and we almost had sex , after that he drop me home. After what happen I feel something different for him . I always think of him, I want to be with him, I want to hug him, kiss him. But after what happened he never talked to me even to meet me never …..That’s the last time that we saw each other. I’m not sure if he’s trying to avoid me, and one time I want to talk to him he refuse he said his tired and he’s going to work early and after that I haven’t try again because I’m scared to be rejected. I don’t know what I am doing but I know…. I feel something for him and I want to remove this feeling. Every time I think of him I always cry. Please help me I need advice. ;(.
