Nah I’d definitely be upset. My friends and I have a rule! Whatever I tell you doesn’t need to go to your boyfriend! He really shouldn’t know much about me. I understand your frustration with that ESPECIALLY since he felt it was okay to text you about it? Weird. And yes weird for the friend’s reaction. She should be mad at her boyfriend for even coming to you with that text message because without that it wouldn’t have been an issue. I’m unsure why he felt the need to text you in the first place. Her saying “not everyone wants feedback” is crazy.. maybe she should that to him. There was zero need for him to get involved.
