My boyfriend said I’m getting fat

So I was getting dressed to go out with my boyfriend and daughter today. I’ve been feeling really insecure about my body for a while since having her and I’m down 5lbs this week, but still have a ways to go.

Anyways... I’m getting dressed and my boyfriend can see me getting sad because of my belly and I’m like “love I just want my stomach to look better” and he goes “yeah you gotta fix it because it’s getting close to that far girl shit” and then like poked at it.

You guys I started crying right away and he says he was kidding... HE IS OVERWEIGHT TOO

I’m just really upset and feel so gross and ugh it just hurt my feelings. Am I overreacting since he said he was kidding?
