AITAH for being fed up with my bestie and her obsession with her toxic ex bf?

My best friend (F36) is obsessed with her ex bf. They dated about 8 years ago and he was THE MOST toxic man I’ve ever encountered. He was tall, muscular and ‘good looking’ yet treated her terribly, always going out for unknown amounts of time, coming home high or drunk and screaming at her. He gaslit her into thinking she was fat when she is a perfectly healthy size and already had some issues with eating.

She is now in a relationship with a fab guy who worships the ground she walks on, but is not a typical ‘hot guy’.

Every now and again she has a crisis about her current relationship and says she wishes the current bf was more like her ex. I try to be as supportive as I can but it’s really wearing on me as I just don’t feel her current bf is deserving of this treatment.

To be clear she mostly refers to their sex life. She misses the way her ex was in bed. I haven’t asked details but it seems the ‘fieriness’ did it for her, and her current bf is ‘not good at sex’.

I haven’t specifically talked to her about how it’s bugging me but I have often expressed that she should be glad she got free of her ex and that her bf is great and she should appreciate him more. We’ve been friends for nearly 20 years and I love her like a sister, but I just feel one of these days I’m gunna loose it at her about how she idealises this unrealistic and completely inaccurate memory of her ex.

Should I tell her or just keep the peace?
