"I was only kidding" isn't gaslighting it's being a dick
gpt
It’s both.  Being cruel to someone who’s upset is being a dick.  Saying it was just a joke and you wouldn’t be upset about it if you weren’t so sensitive is gaslighting.  

The OP actually thinks the boyfriend might be right. Maybe no one else would put up with them. Maybe they are too sensitive….  That’s 100% successful gaslighting.
