How do you get over a person whom you loved the most at one time/still do?

I know what that's like. I'm dealing with a situation very similar to that right now. It really does make you feel like crap, because you keep thinking "What did I do wrong?" and it really screws with your head. It takes a minute to have a crush on someone, an hour to like someone, a day to fall in love with someone, and a lifetime to forget/move on from someone. You miss him a lot, but the best advice I can give you is just move on. It will take a long time, I know, but over time it WILL get better. Maybe not 100%, but it will. I'm trying to do the same thing right now. It's not worth it to be friends with him if he's being like that. You deserve better, believe me! Keep your head held high! I hope I helped..God bless you and good luck :)
