Don’t know how to tell my friend she’s shallow !

My friend has been with her husband for 3 years. He’s a goodlooking guy has a good job. And she loves him ,but when we go out she will constantly say his dick is small. I legit feel bad for him even though he doesn’t know what she says about him. After a girls night in last week I got sick of it and I said how small are we talking. ??And then she said oh what see his dick now !!!????

She said I dont know probably 5-6 inches she hasn’t measured. So I say that’s not small. She said for her it is. Then I told her my bf is 6 and it’s perfect for me. This bitch then says if I like small dicks that’s on me ??? So I said all of my partners have been roughly that size some thinner nothing crazy, and I don’t want a guy for his size. Is he a good person. At the end of the day I can get off with my 2 fingers and that’s definitely smaller then a dick. Maybe she is loose not sure nor do I care .

She just texted me “hey small dick lover , come over we’re having drinks tonight”. I think tonight I will unleash on her im so sick of her shallow superficial views. Am I wrong ? Why is it bothering me so much, any advice
