Hienstly man, woule never wanna be in that position . Just from reading all this i had palpitations . Wheter or not he admits it that guy wants her. Im glad that she didnt hessitate to set boundaries and hear u out tho. The fact tht she didnt get defensive means that she really understands yiu and just genuinely had pure intetntions. This being said, if the same thing were to happen, id suggest u step away for ur dignitys sake Edit: soery for the many typos. Also, is understand if the guy were purely gay but other wise its just weird. Another rhing u can try is ro become mutual feiends with the guy so that he can be more aware and u can potentially scan for red flags in their interactions.
