Feel completely lost because of one person :(

I met a friend online a couple of years ago, and we became really close. Close to the point when we was talking every night via Skype for hours on end. But I love her to bits.. both ways.. friend and in a relationship way. (She knows exactly how I feel and I think she feels the same but the ex means more :-( ) She's recently been debating getting back with her ex and I just feel completely lost. They went away this last week and I felt so lonely without her. Shes stayed at his the last two nights and I just feel like shit. I don't know what to do? I've tried to do other stuff but I just can't stop thinking about her. Even if she gets back with her ex I still want to be her friend, I want her in my life no matter what but I don't know what I can do. We've still been talking by text but it's taking ages to get replies back and I just feel like I am bothering her. Any advice on what I can do?

habe you told her how you feel? if not you need to. Just to see how it is that she feels too. But dont be too upfront because girls tend to get freaked out easily and stop talking to that person.
