Advice please

So yesterday I really struggled with my body image and was talking to my husband about it. I’ve noticed the weight gain a lot and have been really self-conscious. He was working, but tried to reassure me I had nothing to worry about.

This morning, I was on his phone (which I know was probably wrong of me) but I saw a message he sent to a friend saying “if I see one more dime walking around town in a bikini, I’m gonna crash this car.”

I’m a wreck but I haven’t confronted him about it and I don’t know how to/if I should. Literally on the one day I vent to him about how insecure I am, he’s out looking at other girls all day long. I don’t know what to do.

Any thoughts on what I should say? Or am I overreacting?
