You're not hurting me, it's not like he's attempting something stupid or worse, trying to be sneaky about it, and you did come to me first. Your only issues is trying to figure out how to make it work, and convince him it's real for one, that you're interested and it's not false, and then easing the minds of the ones he's already with, because from what I can tell, he's not going to do anything to jeopardize what he has either. I think he learned his lesson from last time.
