Gucci is very right.

Not that my H wants to get back together with me (he lives with OW, lol!) but recently he has been contacting me... asking me if he can come for dinner, texting me from a concert, texting me the next day, writing me a note with my spousal maintenance check and texting me on our anniversary. Keep in mind we have had virtually NO CONTACT since Nov. of 2009. Once he moved in with OW I gave up on him totally. I didn't tell him that of course. I know he doesn't want to get back together (maybe me and him and OW can be housemates, lol!) but I do think he is nervous I am no longer in the background to be his friend.

It might take your W a long time to start sniffing around again but it might happen. You might not get back together if she does come sniffing but it will be the only way to have a chance IMO.
