justalayman, Thanks, I appreciate your comments and everybody else's tremendously. (I quoted you but I wanted to quote Stickyfingers "This statement... IMO...Has to be qualified. First...We have no idea how old the children are. And also how much influence they are under.... Heck, The poster hasn't been back yet....We may never know!" so I wanted to add to the thread and shed some light in my situation.
You are right though, if I give in now, who's to say he's not going to ask for "fall, winter and spring clothes" for years on end.
Until I prove to him otherwise, his impression is that since he pays child support, clothes at his house is my responsibility as well.
Just a FYI, he is also a big advocate of, "if I bought it, it stays here".
