I think it is for the kids and also to avoid conflict. I had a strong urge to ask her to pay the $500 for the flights and may still do so, even tho' I think it will cause conflict. I'm trying to not be greedy and don't want to "nickel and dime" her to death, she does seem to respect the fact I take care of all the bills and she is giving me money for the house payment, plus she has finally given me all the money she has spent on our joint credit card. Those things are progress and I don't want to screw that progress up by pushing for what is "fair" in my mind. But I also don't want to continue to be driven by a fear of conflict. So I'll give it some more thought and if I decided to push her to pay for the tickets then I'll have to suck it up and tell her so. Thanks for taking the time to keep up with my thread HS, the comments and perspective really help.
