Insecurities about future with friend

[Agxx]

To begin with I'm in love with my friend. I'm currently 24 and she is 20.
So I met her at university when I began going 3 year ago, same time as her and we really became good friends, I realize I was in love with her 2 months after we met. But at the time I had so many insecurities so I never decided to ask her out. She later realized I was in love with her but at that time she had a bf and I change the way I acted with her to hide that I still love her, She has been with that guy for 2 years and 4 months now.

To begin with I never been in a relationship and I have really low self-stem so I prefer looking things from afar a let the other person be happy than Involve myself, she is the 3rd person I have become to love like this and well the other 2 I loved long time ago both rejected me so I'm afraid to be rejected and more afraid to lose the friendship I have with her. I began "liking" someone else and I told her and she has been giving me advice, since the other girl I was hitting is friend of us both, so one day I just gather all courage and told that other girl that I'm trying to like that I was in love with her, and well things turn out in a way I wasn't expecting, she was happy and appreciated the way I felt but she didn't feel the same way and also she said that I wasn't really in love with her and that she was only a distraction I was making to forget the love I have for my friend.

Right now my friend is suffering a lot because of him she has been crying for almost 2 months now and she really wants to end things with him. So the other girl told me to go for her for the one I have loved all these 3 years try to really help her forget this guy that is just hurting her feelings, and just tell her I'm still in love with her. And I'm hesitant about it because I don't want another rejection, thou I been for her all this time and I have heard her all that she had to say, She even told me she would go with anyone just to forget him and I have advice her not to since she might get hurt by going out with anyone, She does have other friends that she talks to one guy in particular, she appreciates him but wouldn't go out with him since she knows him how he is that he does what he wants and would make her really jealous because of how he is.

My family knows her really well and likes her and all that, the same goes with her family, We been out of university for a week now and I have spend all these days in her house, She knows me really well too, only thing is that she doesn't know that I love her since she thinks I'm in love with this other girl and asks me how things are going with this other girl. She knows I can tell many lies but she knows how to ask me things if she wan'ts to know the truth so the only way I been thinking about things is that she somehow asks me about that topic so I can tell her.

But yeah don't know what or how to do things.

Also I'm hesitant about it since she still talks with him trying to see if they can fix things, I as her friend support and I'm helping her the best I can, I know sthe talks to other of her friends to also calm down, So the reason I'm hesitant about is waiting to see if things get fix, but also I fear that if I wait too long she will seek someone else, that's why I'm waiting since I fear that if I say something about my feeling I will ruin the friendship I have with her...
I do want to be more than friends with her.
