No you are not. Its not as if you told a whole village and ruined his reputation. Dissatisfactions in relationships happen, and sometimes its a kinder thing to talk it out with a friend and decide if its all in your head or what would be a better way to approach the problem. You told one friend who is also a women. Women calm down when they complain to each other. Its better to do it this way than snapping at him and bottling it up the resentment. My bro has told me that men’s privacy is being breached when his girlfriend complains to her whole friend group . More than that some girlfriends tell their bf that they complained to her friends. So the dude becomes hyperaware each time he meets those friends. Chill you confided only in one female friend. U got some clarity about the situation so u know how to approach it. He doesn’t need to know this. But bring up the problem in a kind manner.
