So my DH's family are a bunch of....well, not nice people. His dad is very angry, always shouting over every little thing my DH does, his sister is very critical but doesn't shout as much. It's destroying him. They get me down a little, but I don't actually care what they think of me, so it doesn't affect me so much. But for DH it's his family, and it's so much harder to deal with.
I'm after some good books about the subject, but don't know where to start. Tried amazon, but couldn't find what I was looking for, really. Any ideas?
