Any guys here that maintained an LTR or marriage while in prison?

If so, any pointers? My brother is struggling hard with his marriage while he's locked up. He's innocent too, but his wife is not being reasonable with him. We're taking care of all of her bills too. The only thing she has to do is take care of the kids. So, logistically, everything is easy for her. It's just the emotional part.

Ladies who have been on the other side, any ideas?
