Moved to "General."
With this kind of thing, ASky, you're often best behaving calmly and neutrally with the woman when around her in-person, and reacting to solicitations by telling her that you're not doing relationships right now, and (if she offers you sex without a relationship) that you don't want her getting attached. She'll insist that she won't get attached; you've simply got to say, "Yes you will," and leave it at that.
Under no circumstances do you want to outright tell a girl you aren't interested; that's a big blow to her ego (it's worse for a woman to be told a man isn't interested in sleeping with her than it is for a man to be told this about a woman, because sex is cheaper for men than it is for women; thus, the statement carries more weight - if you can't give her something cheap, then she must be REALLY undesirable).
Instead, just tell her you don't want a relationship and won't give her sex because it'll make her become attached, and that's what always happens to you with girls and you value her too much as a friend to have that happen.
