SW,

Keep in mind, I'm not always in the majority opinion around here.

That being said, I think "things going well" and "flirting in response to him" are good things ONLY if he's no longer in contact with the OW. If he's still in contact with her, your making those supplicating moves back towards him are only going to enable him to cake-eat, in my opinion.

Who says HE gets to have all the time he wants to "decide" if he wants you?? Go semi-dark on him, and stop being so nice. Let him miss you. DETACH!!!!
