Withdrawn After Prison Release - From Rachel

Before my partner went to prison he was a hard working individual who had been at the same work place for 8 years.
He did something stupid that landed him in prison.
Since coming out all he has done is stay in the bedroom and played on the PS3.
My man is not the same person anymore and here I was thinking that everything would go back to the way it was before he got sent down.
I know some of the posts on your blog have stories about similar things but I want to know if this is just a phase he is going through. He is a bit withdrawn almost like he is depressed and has been out of prison now for 7 weeks. Thanks in advance. Rachel. You can use my real name thanks.
