It seems like girls will be super into a guy one minute and then not at all the next and I don't understand it. If I like someone than I usually like them more and more the longer I know them. If I think I like them but they're different than I thought than I slowly realize it, I don't just suddenly change my mind. Do they fake their emotions until they decide or do they just flip a switch and not like a guy anymore? Is male/female psychology really that different or am I personally just overly sensitive?
