and i am not ok with it. 
i know people do this and its no more than curiosity but i am really upset by it.
He said he was looking up people he knew from the past which i know to be true as old friends have contacted him. Maybe thats what started it off?
But why now? we have been together 24 years.
When i pulled him on it he got annoyed and has deleted his fb account. Or rather taken it off his phone.
I have been less sexual in recent years die to medication and working long hours but id say our sex life is healthy. He does comment though. Is this why maybe??
