Litter Trained Dog Started to Pee Everywhere?

I have 2 Chihuahuas, a 7 year male and a 5 year old female, both have been litter box trained since they were puppies. Last summer the male got out of the house, and was gone for a week, I actually found him, and he seems fine.

My wife and I were going through a divorce, and I have moved. And now he is peeing everywhere. I don't know what to do about this. He gets praised when he does good. I know there is a lot gong on, but I am at the last of my nerves with him. He is a loving dog and seems to know what he has done wrong, because when he sees me cleaning it, he goes and hides. I just do not know what to do about this whole thing.

Help.
