Long story short I'm getting married in 2026, best friend (of 10+ years) has been with this guy about 6 months
I've invited them both round for dinner multiple times and he declines every time but friend comes. He declines because he can't be bothered or doesn't want to not because he already has plans.
When I go to friends house he disappears upstairs - we get on there's no dislike towards each other but merely just a pleasant conversation
At this point I don't want to invite him to the wedding if he can't even bothered to do any of the above?
Aibu to not want to invite? What would you do?
