I was in a 3 year relationship. Well for the first two years everything was great. About 8 months ago she turned 21 and pretty much started going crazy. She would go out and drink a lot. One day she said that she needed some time. It turns out that she wanted to date someone else. Since then we had been on and off up to about 1 month ago. We both decided to give it another try. Things were going great, we just got back from a great weekend in san fransisco where I thought that we had truly come back to not only where we were, but had grown closer together. Last weekend was cool, we told each other we loved one another and seemed cool. Starting on Monday I got really sick, was throwing up and unable to really do anything. Wednesday night she called and asked if I wanted to go out with her and I told her no, I wasn't feeling up to it. Well she went out and hooked up with another guy. I lost control yelled at her cussed her out, pretty much lost my temper. We had another conversation that night and she said she was confused, that she didn't know what was going on, but didn't want things to end. It hurt me once again and I said some mean things. After that day, she changed her cell phone number, and hasn't returned my call that I left on her answering machine nor my email. I wrote her a letter just explaining that I loved her was sorry for saying the things I said, and just want to know what is going on. What I want to know is how can I figure this out, if I should try to do something, let it all go, etc... any perspective would be most helpful.
