Marriage help

So I’m not 100% sure what to do. It seems like some days he cares and other days he doesn’t. I said I felt disgusting in outfits nothing seemed to fit right with my recent weight gain after a baby and he just said stop eating poorly. Which I don’t really.. I try to have conversations with him but he just seems to ignore everything I say or just get mad. Idk how to talk to him about how I’m feeling because I know it’s going to end up with him thinking I’m being mean and it’s my fault or that I don’t love him .. any advice on how to tell him my concerns without him feeling like I’m attacking him I always say I feel like or I statements so it doesn’t seem like an “attack” idk what else to try.
