This guy has said "we must go for a drink sometime" - he's early 60s, never married, never lived with anyone. I'm friendly with his cousin so I've been out with him socially a couple of times, he can be quite loud and drinks a bit more than me but otherwise seems like a nice guy. His cousin told me before this he's had many relationships lasting a couple of years or so but he always ends up "discarding" them then and told his cousin he never loved any of them/ wasn't really into them.
My head tells me I likely should decline a date with him as it's unlikely he's changed?
AIBU - go on a date
AINBU - avoid
