Thanks to everyone for their replies.
I guess I just feel a bit torn because I made the mistake of starting to have feelings for her, and was hoping that we could work things out. Instead, things "blew up" in a spectacular fashion
I know that I shouldn't try and define myself or my level of happiness on whether or not I am in a relationship....
But...for better or worse, I guess I have to accept the fact that I probably won't be in another relationship for several years.
100% of my focus is going to have to be on my back pain, myself, and eventually, surgery and recovery (which will probably take a year or two).
Ain't life grand?
