My ex always tries to come back, and I'm lost.
I dated this girl for about 2 years, I recently graduated high school in may. We talked basically all through high school and dated from march in 2007 to January of this year (2009). We had lots of issues because she was awsome when we first started to date but then she changed as we grew older. Since may of 2008, it has been extremely hard and stressful. We were on and off until January, and I ended it in January because of the following... when I say she changed, I mean that the sweet girl that I fell in love with slowly started messing around and started to lie and eventually cheated on me multiple times leading to several breakups up until the final real breakup in January. She always says she will change and I fall for it, because the what if factor? Every time she has done the same and left me. I have done everything and anything for her, I would not take the bs when I knew what was going on. Her trying to change and come back a lot has really been since November of 2008. But my most recent occasion is the night of graduation, the boy she left me for basically in January, she broke up with and said she was going to change and I really thought she was because she was being super nice and everything. But a week and a half later she went out and the next day completely ignored me all day until she finally said "when i have the guts to tell you what happened, i will. But until then I want nothing to do with you." Leaving me speechless and heartbroken... again. Yesterday I changed my number and only gave it to my close friends, knowing I will start college soon and make new friends, but the purpose of this was so she can't contact me and I do not have to hear of what goes on from the people who thrive off drama. My issue is that I feel I should pursue her still in hopes that one day she will change, but I feel that it is inevitable that we are not meant to be, she also is talking to the boy she broke up with and left me for, but I did change my number in essence of starting a new clean slate with my life. What should I do, considering I love her deeply and I know she does to, she is also going to the same college as I and will try to talk to me again, this I am sure of.
