I hear you about the baseball and your son's request....

It probably does not feel right but you need to interact with Dan alot less. Sorry BBJ...just going with what I am reading here. He does not sound like a very nice person. I don't think he would treat a friend anywhere close to the way he treats you. I don't consider my XW to be a wonderful person but compared to Dan? The interactions we have are ALL very very amicable....if for nothing else my daughter's sake....I am surprised Dan does not get that....I am also worried about how your daughter feels when she sees you bawl after Dan gives you the gears at the schoolyard.....or your son when he sees you guys argue over him....it must be very very stressfull on them.
Like always BBJ....I really hope you meet soemone real nice very soon.
