My fiancè and I have been together for almost 3 years now. I decided to get some sexy lingerie. I put it on to show him and he freaking laughed at me. I've never worn anything like that around him. Am I wrong to be upset that he laughed? I tried to talk to him about it but he just doesn't get it.

UPDATE:

until he can appreciate me wearing lingerie all he's gonna get is me in sweat pants!!
