To pertain directly to you vagrant, let me say:
"Learn from the past, plan for the future, and live in the present."
Have you learned a lot from this whole experience that would strengthen the relationship if you got together? You know, you never truly appreciate the well until the well has run dry.
However, live in the moment. Maybe it's banging other chicks. Maybe it's going to the gym and working on your abdomen. Maybe it's taking a night class on budgeting or working on your career.
No matter what caused you to break up, understand that it is easy to over romanticize good aspects of the relationship, while ignoring the problems and suffering that you may of had to deal with. The pros may seem to surpass the cons, and you might be realizing this as more and more time goes on, which is contrary to the belief that it takes time to get over a relationship. Time can also make you grow more curious as to whether or not this relationship can be salvaged, and the more time you spend dealing with worse women you may start to think that it was meant to be.
If you really want to poke at this, tell her you currently have no desire to be in a relationship with her. Go ahead, respond to those texts in which she says she misses you. Even agree to hang out with her as long as you can be "just friends." Include something in the conversation like "meet me at my house, but don't come in. We'll go to the movies, something where we wont have to speak to each other that much."
This will challenge her and you may see the big picture, learning if this is meant to be or not.
Let me know how this plays out. Hope this helps.
