Lily (25F) and I (30M) have been friends for 2 years. For context, Lily is attracted to women, and I am attracted to men.

Over the 2 years, I have introduced her to a number of my female friends, with whom she has invariably tried to hookup with. It bothers me because Lily is a mess when it comes to dating, and I don't want it affecting my current relationship with my friends.

I introduced her to a new female friend, Kate, 2 weeks ago, and she had been constantly mentioning that Kate is definitely into her. I have known Kate since childhood, and she has never divulged any story of same-sex attraction. They had very little interaction whatsoever, because Kate did not warm to Lily as much as I had hoped.

Anyway, after listening to this non-stop for 2 weeks, I asked Kate did she find Lily attractive. Kate said no, and I relayed this to Lily, hoping that she would knock it off with the assurance that it was obvious.

Lily got mad at me, and said I should not have asked Kate that, as it wasn't my business.

I said to her that it was my business, as it involved a friend who I've known since childhood; that it may well impact my friendship with Kate.

Lily then said I was jealous of her, and said we should take a break from our friendship. Lily doesn't have any other friends, because she cannot keep it platonic.

I want to cut her out of my life, because she brings instability to my current friendships and life in general.

AITA for asking Kate whether she liked Lily?
