thoughtless brothers

My daughter left her husband two years ago. He wasn't treating her right and she couldnt take it any longer. She's in south of England with two young children. I visit and also help out financially as much as I can. Her two older brothers have never visited her. I rhought they would rush to support het imnediately. I am so disappointed in them. I haven't told them that but I am. I'm sure she is hurt.
