Is it normal for my girlfriend to do this
Okay so i have been going out with my girlfriend for 2 1/2 yrs. When we first hung out we'd always have a blast together whether it be alone or out with friends. But as of recent when we are alone she is still cute and nice to me but when we are with friends she likes to be a complete dick to me. For example, the other day i cracked a joke to her when we were with our friends and she gave me a rude look and called me retarted. Then one of my friends says the same thing and she laughs. Not only that but it seems as though she's not just laughing, but adding more fake laughs to it. Also, sometimes ill ask her something and she just flat out ignores me and claims 'she didn't hear me' but someone else could ask a question quietly across the room and she'd here. I'm always as nice to her as i can be and i don't know if she acts like an asshole around people to seem like 'she wears the pants' or to be a billy badass but its realllly starting to get annoying. What do you think?
