So theres this girl that i work with, very very pretty girl, she had been kicked out of her house and was sleeping in her car, Now trying to be a good person, i offered her a place to stay, got the air mattress from my parents house set it up in my room and what not. since shes lived here we have hung out everyday and i find myself having feelings for this woman. and since we went out to a very nice dinner shes moved from that to my bed(nothing physical has happened, not even cuddleing) shes not paying rent but i feel like i might be being used, any thoughts?
