Ive been pretending to care about what people tell me but i actually couldnt care less

I have been hearing about my friend's talking and dating stages the last year, i have heard aproximatelly about 30 people just in 2025, every single detail, about him having fun and enjoing moments with them till the next week sayibg they are fake people, hiding behind masks (dont think im sum like againt dating, ofc not, i enjoy my dates and stuff) and on top of that i have him talking 5 out of 7 weeks about missing his toxic ex while being on dates or "relationships" plus sending me selfies every week with his new "love". Adding that he is still my best friend and i care avout him and we havw fun when we go out, but this has to stop, ive tried telling him kidnly and not straight to his face in a bad way but he wont stop.
