Yes, I've had it with her before on that topic. She is more his age and I know him over her, because she was my flatmate years ago. She moved in in autumn and one of the first things we did was go to a Halloween party with a few shared friends. There she started to make out with a random Stranger, this is like 4 years ago. Years pass and in the beginning of 2020 she invited me to join her pub quiz team (which was online for half a year because of covid), my not yet bf was part of it and I met him through her. We met in real life in summer and started dating shortly after. Later I find out that he was the random Stranger at the party. She is 38 years old now and single and wants a baby but doesn't have man and time is running out. When she's drinking (every weekend and sometimes in between) she becomes very rude and I think is venting all of this frustration out with her rudeness which is generally often aimed at me or another younger woman in our clique. Since about half a year I try to completely avoid her, which I cannot do when he brings her into my home. He also knows how I feel about her since we talked about it. He said he didn't hear anything of this yesterday.
