Grow up. You chose the wrong guy on the simple notion that he asked you first? ..
..
Did you ever ask yourself what YOU wanted ? You do all women a disservice by simply acting like the passive dolt that gets manipulated into a situation. Take control of your life. ..

Seek out those that YOU want to be with. Ignore those you have little or no interest in...

You're young and probably don't have much experience with this kind of situation. Now you know to consider what you want and not just who is asking you out. And the reasoning "I wanted a boyfriend" will not necessarily lead you to having a great boyfriend who you really love to be with and have fun with. So don't just look for A boyfriend, look for THE boyfriend. This situation might be too messed up to repair, you don't want to mess with these guys' friendships, although I'd say that Bryan already did when he tried to stake a claim on someone his friend clearly already had a thing for. I'd just try to step away from them for now...

You have a pretty big mess here and I am sorry to say that there is no easy way out of this. You can't help what you feel, so I think it would be best to tell both guys the truth and see what happens. I get the feeling you are with "Bryan" just so you won't have to be alone and that is a pretty crappy thing to do to him. You should probably end things before both guys end up hating you. Sorry if it seems harsh. Its never good to get in between friends and if you care about "Edward" you should respect that. Maybe you should take time to be alone and let everyone think things over. There is nothing wrong with a little alone time to think about what you REALLY want, trust me. I hope I could help...
