Most Helpful Guy
No, most women overreact like yourself. Face it, a lot of guys can be insensitive and It's up to you to determine whether you can put up with it or not. You'll see that in a lot of guys and what's important is to determine when a guy is joking vs. being deliberately hurtful which is what you certainly don't want. I've tended to be sarcastic in relationships myself and appreciate a woman who can tolerate it and see past it, but everyone is different and some can put up with it while others cannot.
