What do people think?
Ditto to what's been already said. Insist on openness or postpone indefinitely.
I try to think of it this way--if I'm entering into a relationship with someone, I'm also entering into a relationship with their partner/lover/(insert favorite word). It might not be a friendship or intimate, but it's a relationship. That implies a certain level of responsibility to that person.
