I told her Friday that I really like her(and I do), she told me that she has a bf(I already knew but I wanted to know just in case she has feelings for me) and she asked me if I drop the feelings I have for her and go back to being her friend at the time I said no I don't think I can.

Mind you we been flirting crazy for like 2 weeks so I was confused. So Tuesday(which is today) She completely ignored me but I didn't Dwell on it at all. It seems she was more depressed then I was. So anyway After school she talks to my boy who gave me inside information that she said her relationship with her boyfriend is not so good(long distance, another country) and that she has issues in her life and just really needs a friend. So there's a 50/50 chance according to my boy that she will tell me this tomorrow or cut me out of her life completely as a friend since I already told I can't.

Now to be honest everyone is telling me to just be a friend to her but meet other people, but this girl I really like allot and it just feels right. I don't want to mentally torture myself like I have by just being her friend because I will always be left wondering if she will change her mind, and I can't just "drop" feelings for her I isn't a robot. Because truthfully I don't think I can just be her friend. So this is what I plan to tell her if she asks just to be friends.

"Look while I have no doubt in my mind what so ever if you gave me a year we would probably have a brother and sister type relationship easily I just can't do that because I still have feelings for you maybe in the future when I stop have feelings for you but right now being friends with you would only intensify them. Life's too short and I don't want to chase a girl that I have feelings for but she doesn't . It sucks now and you have no idea how painful it is to do this, because I never asked to start liking you it just hep end, but I know that in time I will be much happier instead of always wondering years down if things would ever change. I hope you understand why I can't be your friend as it would just make me like you even more because your beautiful, smart, and have a great since of humor. I isn't one to hide how I feel. I'm doing this because I like you way to much I hope you understand. I hope things continue to go well between your boyfriend and you but if things don't work out feel free to contact me"

Would this be a good thing to say? Or am I being to selfish by not being her friend. How can I lose feelings for someone other then trying to find other girls because no other girl in my school I like even remotely as much as her. I told her how I feel already and she doesn't feel the same way. I get that but I can't help but wondering if I stay friends with her things might change( yet I know logically it just doesn't happen) any tips?

If you already knew she has a boyfriend, then you need to respect that.

Be her friend, if that's what you want. With no romantic expectations.

If you want something more, then, don't.

You can be her friend forever, if you want & its good for you.

If you want to be her boyfriend, or have expectations, then back off that. That's not a friend.
"she told me that she has a bf(i already knew"

Good friends are one thing. Romance is another. The best ones are unconditional.

Go out & date more.

If you can't be a real friend, leave her alone until you can. Its called rejection, of affection, and you move on and get over it when it happens to you.
