Stuck in a probably common teen mess
Hello I am new here and hope its not wrong if I come straight to the point. I'm currently 19 and will turn 20 in next two months. Since I was 16 I had this huge crush on my college friend whom I grew good friends with because I didn't believe (still don't, tell me if wrong) of entering a relationship without knowing a person. I proposed her when we were 17 which she declined but we stayed friends. I got into another relationship where I dated around 7months but it turned out it was one sided which really crushed me.
Surprisingly me and my previous crush joined same college for graduation. Now 18, she became my closest friend and helped me heal through my break up which took me more than a year cause I was damn serious. During this process everything I used to like about her kept coming back to me. I thought it was a rebound thing of my mind so I didn't ask her out again. Also I was afraid of losing the closest person I had, and mainly who understood me. Being a poet I just kept spitting my stuff in rhymes and raps.
We are 19 now and I'm done with the rebound thing and all and the only person who captures my attention is her. I have tried flirting with others and get into something casual but I couldn't go forward to any possible relationship because all I can think of is her. Our families too have grown close to each other. As far as I have even become friends with her distant cousins! Now I'm not thinking of marriage or sex, but the thing is I am madly in love with her, all time I think of her, whatever I want to do involves her but I know she is not into me and considers me only as her close friend.
I try going away from her knowing that I'm just hurting myself but being classmates and staying in vicinity we have to do projects together and I can't run away from her. I feel no better than a devil when she asks for my help and I have to refuse her so I just can't do that. How should I be with her and yet not love her when all I think about is her and most time I spend with is her too?
