Love advice..please help. ?

Hello. Let me tell you my story. I have been friends (best friends) with this guy for over five years now. I have liked him as long as I can remember. We've both always had relationships though. Recently, he told me that he was in love with me. He is single and I am not. I've already had feelings for him for so long and everything got really confusing. I love my boyfriend that I'm with but now that I now that this friend feels the same it is so hard to just let him go. I know what you're going to say, make up your mind. But it isn't that easy. Someone you've loved for a very long time and a boyfriend that you've known for less than a year? I've told my friend countless times that he needs to find someone better because I'm not ready to give up my boyfriend that I have now. But it is still so heartbreaking... last night we talked and I'm letting him go... I don't want to hurt him anymore. Today my chest hurts. I have a headache because I feel like I'm missing something... we haven't talked all day. He keeps telling me that he is fine but I know when he is lying... any advice on how I can stop loving him? It hurts to much.

My personal advice is to stay with your bf but DO NOT LOSE THE OTHER GUY AS YOUR FRIEND!!!! I have been on both sides of the guys side and either way it is heart wrenching. If you break up with your bf, then you might miss out on something that was really good, but if you lose your friend, it would be alot harder to have him as a bf later if you still wanted to be with him. you do need to be stern with him though and let him know that, for the moment, you will be nothing more than friends. I know that it will be hard no matter what you do, but I think that would be the wisest choice. you do not need to be asking the guestion on how to stop loving him, but start asking how can you be the best friend and gf at the same time. Good luck to you. it will be tough.
