My girlfriend of 3 years moved out of our home together because of things that I have done. She said that she will be back she just wants to get herself together but every time the subject comes up she doesnt want to come back and when I ask her to see me she says no. She left half of her stuff and she said she did that on purpose because she wants to come back. It has been two weeks I miss her so much what do I do and how much longer until she decides to come home. Is there something else that she is not telling me as to why she will not come back yet?

Well im not going to ask what you did, because that'll just confuse the issue. But she is obviously upset, its a very good sign that she says she wants to come back and left her stuff, because it shows a willingness to forgive you.
I think you should give her the time she needs and not call as often, let her know that you want her to come back and that she can call you to talk at anytime, but then you need to get out there and forget about it, more problems are caused than solved by sitting next to a phone waiting for her to call, go have fun, try to get your mind off things, when she contacts you, let her know she is wanted, that you are sorry, and that she can take all the time she needs because you want to wait until she feels ok.
