I have been dating my fiance now for 3 years. In my opinion his ex is just crazy. Seems to me like she only does for the kids when its convienent for her, always saying she is the one that does everything. When in reality she only does when she wants to. My BF and I have had several "discussions" about her and the lack of "parental" responsibility, however he just now started putting his "foot" down with her and not doing all the running. The problem is, I don't want the children to suffer any more than they already have. Unfortunately, she does use him as the "bad person".
