Oh and even if it were negging; that would make him dysfunctional and nasty and a dickhead and unpleasant and someone can't be normal, well balanced, kind etc.
So why would you want a relationship or even fuck buddy situation with someone like him?
You also seem to be saying he was only offering/interested in a fuck buddy situation .
basically a loose acquaintance who is looking for sex etc. rather than a potential relationship
You also mention he was willing to do stuff with you if he was bored.
This does not work for women in my experience.
At all.
Fuck buddy and fwb situations tend to benefit men and work for men, not women.
I know very very few women who manage them and are happy at the end.
Usually it's when they don't care about the guy, don't have feelings for him, don't see him as potential partner material and - most definitely - don't have him on a pedestal.
They use him to scratch an itch and have their sights set on other men for a relationship. Or they don't want a relationship/it's not feasible due to factors like kids, looking after people etc.
For the most part, I wound never ever recommend a woman get into a fwb/fuck buddy situation.
But even if they did, the dude would need to be a lot nicer and kinder and more polite and respectful than this dude.
