I'm sorry, but ya'll can't be working that WELL together, if he makes you feel like crap for receiving CS and is NOT paying it!

Quit making excuses for him. Until the withholding comes through...which could take a couple of months...there is NOT reason why he can't pay the CS...THROUGH the state...when he gets paid...until then.
If you air your dirty linen in public, expect people to comment on the skid marks!
