Another good question that should probably be asked at this point is what would you do if she contacted you again? If she would have responded to that request for forgiveness? Any tools in place there to be prepared for that or expectation of how you would react? How recent was this?
You haven't spoken to her to really know where her healing is, really did not give her a chance for the same closure. You are only receiving information through third parties? Am I correct about that? Which I would not think is a good thing at all.
If you are currently seeking dates on that online dating site take it very slow and easy. You would not want to bleed this over into anything new. This still sounds very alive in you and you could be setting yourself up for rebound with the new person never quite reaching the level of this last relationship simply because you have not healed or identified your reasons for this relationship.
Just some observational points. Hanging in there?
