He told me “I’m supposed to be a girl”

In the past 2 years.. Out of all the shit we do to each other, I burped like... a normal ass burp too close to him apparently because he told me “you’re supposed to be a girl” I got upset. We argued. And he went and slept in the guest room. We burp, fart on, lick, and be goofy all the time and it’s like today a switch flipped. I have issues with comparing myself to other girls. Thanks social media for that one. And it just made me feel like I’m not this always beautiful looking, flawless, perfect body, hair and makeup always. I know it’s not realistic trust me.

I told him, by him saying that I feel completely insecure now. He says I’m being a child about it. I’m well aware he shouldn’t have said that, and no I’m not going to break up with him over this. We have a 4 month old so I’m dealing with Postpartum hormones & I’m on my period hormones so I could very well be over reacting

I already told him I felt insecure. And I told him to get over it every person on this earth burps and farts. What else would you lady’s tell your man if he said this to you in a very rude way?
