Yeah, I've had that problem with my ex before. There's not much you can do, other than record it and use it against him in the future. But I always saw it as a blessing...to get to have my kids more...and no stress of dealing with ex. Now I say that all of his visits are contingent on his money being on the line (he's from out of town so has to buy plane tickets etc.) and I'm free to make whatever plans with the kids that I want unless he shows me the actual ticket confirmations. But if you're all local, it's a different story. Hope you manage to work things out!
