He treats my husband as a counselor. It drives my husband crazy that he was once a child carer of two severely disabled parents in the 70's and now feels he 'has' to be there for his elderly dad again when his dad is using him for all his moans by telephone twice a week. He desperately doesn't want to abandon his dad but his dad really takes advantage of him and will play the guilt card at every turn. He has got himself into a position of isolation and terrible loneliness. All conversations about nursing homes seem futile and my husband gets visibly depressed after hearing his woes by phone. Equally he feels guilty if he doesn't listen to his dad because he has no-one else.. Any advice on boundaries in this complex case appreciated.
