Oh they know how much he gives me and they also know he's behind and not trying to catch up. You're right, they do suck. But, what can I expect from a guy (FIL) that screwed his then wife's best friend (now the Stepmom)? Shows how much they care for marriage vows.

You're right though. I will keep paying it, keep smiling and being nice to them. I know I won't be the one to regret my actions if this marriage comes back together.
