Input: This incident involves three people. Me, Person A, &amp; Person B

Person A jokingly mentioned he wanted me to invite my girlfriend’s little sister to a group event all of us we were planning. In response, I said that I find it weird to have a friend date my girlfriend’s little sister as I find it one step detached from being eskimo brother. I realize this may be an unpopular opinion, but I only care enough to the extent that I wasn’t looking to actively set them up. If they were to meet organically, more power to them. 

In response, A found this strange and told me that he thought there was nothing wrong with being eskimo brothers with ex-girlfriends, much less sisters of a current girlfriend. In fact, A went so far as to say that he would be okay with his friends being eskimo brothers with his ex-girlfriend. Surprised, I asked A again if he was hypothetically okay with our mutual friend (Person B) being eskimo brothers with his ex-girlfriend. He in turn found this comment to be of low taste and was quite upset by it and went so far as to say I had low EQ for bringing her up

I’m curious what Reddit’s opinion on this is as I usually quite sensitive around bringing up ex-girlfriends. In my opinion, I wasn’t out of base bringing up A’s ex-girlfriend in this context as he essentially said first that it was okay

bringing up my friend's ex-girlfriend in a context that he said was okay
