I dont know if you are serious or not. I didnt give her place to sleep and food in exchange for sex, I gave it out of good will with ulterior motive from my part. It's not like I told her "I give you this stuff if you have sex with me". We were watching a movie and I made insinuating gestures at her. She responded positively to my gestures and we ended up having sex. This is the way I might have approached a "normal" girl as well. so no, I dont think I made her a prostitute. It is borderline paying for sex, I know. But it is questionable in this case for sure. I dont know whether me getting her the room and food made her have sex with me, or if she had sex with me without the stuff I gave her altering her decision. Probably it did, I dont know. But it's not as clear as you make it sound.
She came from ukraine with some dude to be his wife.. So if someone made her a prostitute I think her ex-husband beat me to it. Call me cynical, but I doubt it was true love with them. She probably came here with him to get a better life (which didnt turn out too well).
