Maybe you should read your own post. You said you broke it off and you should have just said you needed space. So, she went on about her business. After a long time together and you just cut her loose, are you really surprised that she's ignoring you? Then you can't figure out why she's ignoring you when if she just needs space she should just say so? Did you? YOU don't understand how you can cut a person out of your life that easy? But you did it, right? You dumped her. I agree with one thing you said... you are confused. I don't think anybody could say what she's doing right now but whatever she is doing it's no longer your business. Back off the girl. If she does have feelings for you and decides to contact you she will on her own time. Your constant aggravation isn't going to make things any better.

Kinda goofed there man. From the sound of your post you just randomly broke up with her during a great relationship? First off when you start to get confused you take a step back and assess them, second you talk to her about something that is potentially bothering you. Third, when you broke up with her she might have gone and hooked up with someone else, seems to be the best way to feel better after getting dumped.
But she could just be taking her time. Best bet is to leave it be and if she wants to talk to you she will. If you really want to get through to her. Write her a letter and put some thought into it, and explain your mistake and why you want to be with her.
