Venting I don't understand my brother

[cosifantutti]

A few weeks ago I rang my brother to talk about suicide. His wife answered and I asked if she could get him to ring me. I said I wasn't suicidal right now but wanted to talk about suicide. She told me that me she'd tell him but that he was very tired. I spoke to him briefly a couple of days later but he was at my Dad's and so we couldn't talk but he said he'd ring me.

He hasn't rang. Yet out of everyone I know he really understands me and when we do speak he seems to really empathise.

I don't understand why he wouldn't ring regarding this. Is it that he's full of good intentions? Can anyone suggest why he wouldn't ring?
