Remember that she may be lying to you to try to manipulate you into admitting to her that her boyfriend cheated on her with you but instead of asking you outright , she manipulates you into it by claiming STDs and then asking if he got anything from you , I know he cheated on me with you she may not even really know , but suspects , and is trying to get a rise out of you to confirm her suspicions . I ' d suggest never responding . I suggest staying far as hell away from this situation and these people . Cut yourself out of this situation , avoid them , don ' t bother arguing with them or giving them a piece of your mind , these people are insane and that makes them dangerous on an interpersonal level . Don ' t bother trying to tell her off or use her to make yourself feel better by venting anger it can just end badly and will probably not help much if at all . what could possibly be helped by engaging further with these people ? avoid them and go get yourself checked for STDs to see if you got any from her . this can all just result in extra stupid shitty drama . avoid avoid avoid . abort abort abort .
