To me it seems obvious that you know not to get into a relationship with her, and if you one night stand her it fucks your reputation at work and with that whole group. I guarantee she will bad mouth you because shes already hurt.
Options:
1) Fuck her and continue to fuck her then cut off contact. (would not recommend because it will crush her when shes already at her worst)
2) One night stand her then say it was a mistake and it your relationship should be strctly professional (better but not recommended)
3) STAY AWAY FROM PSYCHO BITCHES (at least ones u work with). This is her she is emotionally fragile, paranoid, and self conscious because of being used many times before. She is not confident and looking for LTR. If this is what u wish then pursue, if not then stay away because u work with her. (This is highly recommended)
If she wants to fuck you can still fuck her as long as its stated before hand you are not interested in a LTR.
Manners must be used in any relations with females you work with
