anyone else's husband this difficult to understand?

I spend most of my time nipping round to Dear dad to do his ironing and have a chat, keep him company, take him shopping and do some cleaning, which I love. he is 86 and very kind and independent, I think the world of him, As A retired business woman I don't go out to work and spend the remaining time cleaning my own home and cooking for my husband, etc.Having always been the devoted wife and Mum,... Therefore have no social life apart from seeing Daughter , son & his wife and granddaughter now and again.
A leaflet came through the door about a coffee morning group starting up for people of 55 and over , just down the road from me in the town centre, I thought, Great, I'll go and see what it's like, a good way to make friends & have a little chat away from housework duties, make a nice change. When I mentioned it the other morning, my DH had a sudden outburst...'you don't know what sort of people will be there,...there must be a catch, you just want to go and meet men...I was shocked to say the least...& told him so.
aibu to feel that he's being controlling and selfish, after all, he can jump in his land rover and go off anywhere he likes..& when, I'd appreciate your opinions on this girls, ..feeling rather at a low ebb right now, xx
