Maybe she's doing what most girls do before they leave their BF and try to find something soft to land on when they finally make that jump. Chics rarely leave a dude with out having a back up plan. It helps them cope and move on emotionally. Not saying you were that guy but you never know.
I mean how many of you dudes would be cool with your girl hanging out at some other dudes apartment by herself? How about on the dudes bed?
She's hiding that from her boyfriend breh, guarantee she doesn't tell him. You're a safe fukk because you're right across the hall. How much easier does it get for her? Now you probably blew your chance by acting like a teenager...
Unless, she really does feel that "safe" around you like a gay friend..
she might think you're gay breh...
Clear the air asap, tell her you enjoy her company and that you thought she was going to tell you she was a tranny. Also, don't forget to tell her you like vagina.
Remember hot chics usually run together. She may have friends you can
good.
