I don't really like sarcasm either and that was a big issue in my last relationship.
He told me I was too sensitive too but I felt his comments were verbally abuse. Nobody likes being made fun of or put down all the time.
The older I get the more I think it's just a form of thinly veiled aggression.
Yes, we should all have the ability to laugh at ourselves but when you tell someone not to speak to you in a certain way they should also respect your wishes.
