Just read all the posts.
No offense, but the responses are telling you "no" don't go there.
But you really wanted to hear "yes" (at least I get that by your 2 replies to the responses)--and that is not what you are hearing.
So you might have to go w/ your gut and what you want to do. Not that I would encourage it. But I am not sure you wanted advice as much as support to "go for it" and meet up and share your feelings.
So you have to make the decision--and whatever that is you cannot later go "would of, could of, should of". It is what it is.
Good luck to you and your ex--whatever you decide.
