I was in a 6 year relationship, and when we broke up...it was because he wouldn't commit.
He tried to contact me three months after the break-up, but I KNEW that I was not ready for that. I loved him then, and I still love him now, (10 months later). I didn't not contact him to be hurtful, but rather to spare myself more pain. He's "My Favorite Mistake" to date. I have only fond memories of him, (as that's what you remember when you focus on what you're missing out on).
Since this man...I have had a series of failed dates...I'm just trying to get my heart back into its "happy place."
Good luck. Don't read too much into it. You could question the way things have played out until your blue in the face. Would that make you feel better? Just be glad you're not wasting more of your time with her, instead of allowing yourself to be open and available for the RIGHT relationship!!
