Wow. We Lexicon I know this may sound generic because most people that respond to stuff have a connection with what the person is talking about but, I know what you mean I have been there.

My first suggestion to you is to throw out any pictures of her or anything like that. I don't suggest that you throw out CD's and stuff because they are quite expensive, but the ones that remind you most of her take and put them in a box and give them to a friend who you can trust to keep them away from you no matter what you say or do. I did this, I gave my Counting Crows CD away to my cousin and no matter how much I told her I wanted it back she didn't let me have it. It's a good method I encourage you to try it. As for radio, why are you listening to it? It all sounds (as my friends and I called it) System of a NickelCreed type music, it sucks, just turn it off.

I had the same situation with a girl (Although she didn't treat me badly) who had the ability to just move on forget. I think it is a skill that we are not able to learn unfortunately. I know that it sucks a lot and you wish and think to yourself about how you hope that they are thinking about you, but they are not, and it's the harsh reality. My question to you is do you have a lot of free time? The more time we give ourselves to think that worse it is (Or at least from my experiences). So try to hang out with friends or distract yourself with a hobbie that makes you think or be distracted. Although if you can figure out a way to confront your feelings and solve them, that would be faster for sure but I have no idea how you would go about doing that because I am still hung up on this girl as well. If you figure it out let me know.

I hope this helps and know that I am feeling the pain the same as you and thinking about you. No BS here just full honesty.
