My situation seems a little like yours. XH had a EA in 1998, lasted thru 1999 or 2000. D in Sept of 2001. Calls me everyday to say hi. He has been on a few dates but can't seem to get past caring about me. He says there is so much history between us, he can't seem to let go. (11 yrs together). Calls me hon every time he hangs up the phone. Feels he has made a mistake with D'ng me. A lot of words but NO action. We share joint custody with our 3 yr old D. I see him at least twice a week and every other weekend. He gives me hugs and last night he kissed me on the cheek. I NEVER initiate anything; no phone calls, no OR talk. He told me he will never remarry; he has a hard time with committment. Some days he is very caring other days he gives me excuses why he didn't call sooner or why he can't talk long on the phone. There are days I think wow, maybe there is a chance for reconciliation but then usually a few days later he is off in his self absorbed world.
I have no advice for you. Just wanted to let you know you aren't alone and buckle up tight - the ride isn't over!
