PROBLEM WITH MY GIRLFRIEND?!?

shes been acting really off with me recently. i mean i bought her about two months ago and i treated her well, like i let her go out into the FRESH AIR with me. and now because i wont introduce her to my friends because shes f*** ugly, shes being a b****. i mean its not my fault she was born a gremlin. what can i do guys? i can't get a refund on her and she's pissing me off.
