My first serious girlfriend just broke up with me (I'm 25), we were together for almost 5 months. At first she wouldn't really give me a reason, but I had a few theories why. So we e-mailed each other a little bit (she said she'll be ready to talk about it in time) and she basically said it wasn't my fault, it was all on her. She said she started dating again too soon. She also said she felt early on in our relationship that we may not be as compatible as we should be, yet she told me she loved me. So I don't believe her excuse, and it really hurts to not know what the reason is.
