wi, let him "balk". if he wants what's best for his children, he'll balk and get over it. if he's responsible for medical and has insurance, i'd do it in a heartbeat. make sure with atty just what financial responsibility would be yours and go for it!
sounds like he's balking at alot...this will be something worthwhile for him to balk over.
gl. let me know. this is something i would definitely do though...just my personal opinion
