So I am in a relationship of nearly 4 years. I'm in a group chat on whatsapp with a few of my old school friends and today a guy friend complimented my breasts. I thought it was only right to tell my boyfriend about this because we dont keep secrets. My boyfriend is basically annoyed at the fact that I just brushed it off. His opinion is I should of had a go at the guy who complimented my breasts. Which I dont really think its much of a bog deal because at the end of the day, its not like I have cheated (I never have). Am I in the wrong?
