He will thing me to come home as he's forgotten them again or he'll knock on the door so I have to stop what I'm doing to go and let him in. Tonight he walked the dog and I was hanging curtains and heard him get back so I opened the window and said you'll have to wait if you've forgot your keys as I'm busy. I don't know if I'm being unreasonable but this has been going on for over 5 years and even when I don't rush back right away he says I'm unreasonable to get so angry about it and why can't I just help him and not complain. I don't even know if that makes sense but honestly it drives me mad I have to stop cooking tea etc to go and let him in. So aibu to not want this to continue or should I chill out about it like he says ?
