Obviously it's not very realistic to believe you can be 'friends' with somebody who's betrayed your trust. Even if it is your W. On the other side of the coin, it's not possible to be totally indifferent to the Mother of your children. We're not the one's who walked away with our heads up our arse.
I like that term 'neighborly nice'. It really does describe that happy medium you need to be at with W.
Even after 3 and 1/2 years of separation, my ex will still call me out of the blue and use our Son as an excuse to sing her blues to me. She misses that emotional shoulder to cry on. I don't really think she lets the OM into her REAL WORLD, she knows that's F'd up and might scare him away. I think they are both at that.. 'I can't pass gas with him/her around now' stage in their relationship. There's no room for that in a story book romance!
Sorry if this sounds a little crewed, but your basically her old gas bag for now. Don't let that surprise you and don't read to much into it. She simply takes a emotional dump on you and flushes you when she's done. She really can't do that with OM right now because it would ruin the carefree romance part of the story.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
