I am glad you are feeling better. I can understand how your H feels about bartending. I did it for 6 1/2 years and then bartended and waited tables for another 3 or 4 years a couple of years ago while in community college full time.
It is fun at first, then after a while, it gets really old. Especially when you are tired and want to go home and you have to deal with people who have been drinking and some are incredibly stupid after a few drinks. It makes you watch what you are doing when you are out having a few.
It is so nice to hear from someone who has won the DB war!
Everything happens for a reason, maybe Dad needs to find that it isn't better out there, he needs to realize how good he had it here. Maybe he will find God and that is the most important thing when he finds Him he will know he is supposed to come home.
