Chic, anything is better than the old push and pull arguing...don't worry about him "abusing Ritalin"...he hasn't even gotten his foot in their office.....sheesh...let him go and start seeing the therapist before you find something new to worry/obsess.
but make it known, that if he gets employment of any kind, 1/2 of his paycheck goes to the household expenses...if this is what you want to do.
it sounds as if he might be mulling over the issues you have been suggesting and this is good...so is applying for jobs and doing any kind of work.
hope you have great vacation with no more stress.
