How is she a prostitute?
I'm personally not going to lay up with a guy that can't or won't do anything for me. Take it how you want to take it. If you know I need a coat, get me a coat. If I see a sweater or anything my boyfriend would like or need, then I'm going to get it. If someone is seeing me, then yeah it's an obligation. We have an obligation to look out for each other.
