this guy

i have recently met this guy. ( let’s call him J). i have gotten to know him through friends and we have been talking for about 3 months. just before we met each other, he had broken up with his girlfriend and we started talking to each other, we were talking all the time and i told him that i wanted to break up with my boyfriend because i wasn’t happy. he gave me some great advice and a few days later, i ended it with him and J was there for me. a few weeks later we had such a great friendship and we had told each other things that we haven’t told others. we were talking one night and i said i was watching this show about paramedics and how i wanted to be one and he said he did to. so we would always tell each other that it’s on and we would text the whole way through the show. and that’s when i was starting to get small feelings for him. a few days later he was listening to some music and he sent a bit of the song and it went like this “cause you want me and i want you” and i was with my friend and she said that he might like you. it i wasn’t sure. later that night we were talking nonstop about the same music that we like and he made a playlist for me to listen to. so we would always listen to the same playlist and i would tell him to add songs in and he would always recommend songs to me and he still does. then about a week later he texts me about his chick he says he likes and i was so upset. but i was there for him and i helped him out with her. then a few days later we were talking and he was really upset and i said “you ok” and he just vented to me. then i gave him many paragraphs back and he comes back to me saying that he actually started crying when he read my paragraph and said that he appreciates me and that he is so glad that someone actually gives a shit about him to write him that much back to him. then i asked him how his chick was when he was all better and he said that he ended it with her because she want the right one, and i was filled with joy because i thought that i actually had a chance. we met again at a gath that week and we had so much fun with each other. we were in the backyard playing jack in the pack and he comes in between my friend and i and starts elbowing me for a little bit of fun. and when i sat down he sat next to me. we kept talking after that until recently he has gotten to know this other chick and apparently was getting in with her but one of his friends said that he didn’t end up getting with her. and now he is being all flirty again. my friends say that i should tell him that i like him but i don’t want to ruin the friendship we have. i need some advice about him. sorry this was so long x
