Diane,
I just wanted to drop by and send you a hug. Everyone has given you so much good advice, I really don't have much to add. I agree that you need to do what is best for you if seeing him is to hard, write him a letter explaining that. Hopefully he is doing something worth while with his time in jail, I would encourage him to take some classes learn a new trade while he is there, I believe PA offers some really good educational courses in jail. All we can do is hope. How long is he in for if you don't mind my asking?
