My ex-gf and I split for the second time, this time she split from me. 2yr relationship. We were going to get engaged but I wasn't quick enuf. So a month passed of me trying to get her back and we actually went on a date 4 days ago, (I think she may have thought I was going to ask the question - hell we kissed and laughed and had fun) but I irritated her by IMing her at work the next day, she might have gotten into trouble, and now she won't return my phone calls. I was really good to this girl and she punishes me with no apologies, blaming me about everything and everything I have done for her is noble. I am getting SOOOOO aggravated with the no contact thing when I have been so good to her. It's flat out pretty mean, I would never ever cut off contact for someone I loved. Im ashamed

No amount of noble behavior or good treatment can make someone other than who they are, it does not change their needs. The "good treatment" is not meeting her needs. What you consider good treatment, she may not. What does she say that you are not hearing? If she says that she wants you around and you send flowers... You aren't around.

How old are you..

The whole "wasn't quick enough" and the "aggravated her so now she won't pick up" seems rather immature on her part. If it was enough to set her off, then there's definitely something else that's wrong.
