When he texts, every time for 7 days, wait two hours to respond and text back, "real busy. need something?"
if he texts something emotional. response: "too busy for that now. have a good day!"
DO NOT ENGAGE AT ALL on this for at least 7 days. also bump him to voice mail and let him have panic attacks. you have nothing to lose.
also toss in some 24 hour waits for any return to your text. your good-girl bit of returning texts immediately is not winning you any respect as far as him texting you back immediately.
as far as contacting ow, maybe if he was sleeping with her you could have a mutual acquaintance let her know he is sleeping with both of you. lol. but since he isn't, not sure if any contact is helpful. in this sitch, it might give them a mutual drama because she doesn't care too much anyway and she'll leave town soon as you said.
what you have to be prepared for is he may go looking for another OW "fantasy love" to avoid his issues. at that point, deinitely dump him. he could waste two years of your life with this b.s. not to be harsh, but this may be a situationa where you have to walk away totally before he gets a clue.
