Need some serious female advice
So my situation is I am in love with my best friend and it's killing me. I'm 19 years old but she has been my best friend ever since I can remember. We've also dated when we were younger in about 7th grade. The problem is she has a boyfriend. They fight all the time and she always comes to me for advice. I need to know how to tell her I love her with out freakin her out. She knows I have feelings but not even the half of it. The way I feel about this girl is unexplainable. I recently was in juvenille hall for 8 months and she wrote me the whole time and encouraged me to do better. The only way I can tell how I feel about her is that I would die for this girl. I would marry this girl today and I know I will never get tired of looking at her beautiful face. When I was incarcerated she is all I thought of. And when I got out and she was back with her ex it killed me. And I'm getting the feeling of running away because I can't stand to see her with him but I could never leave her..
