Hi sis, I have been reading, seeing you hit a low. Do not underestimate the fact that "your date" hasnt been eager to take it further with you -not yet at least-, it kind of pushes you to the direction of the familiar and what you've known all yoru adult life:Dan.
I also see that Dan's response was a message to you as well. Sounds to me he wants you to realise he has come to terms with the fact you arent going to be together again? Makes me wonder why he likes to pull your chain every once in a while...
I agree with those saying you will always have some kind of affection for your xH.
