Talk to your husband. He loves you for who you are. He doesn't even know why you're upset. He pob. thinks he did something wrong.
Listen, I gained weight since I was hanging out with this guy from years ago. He's now back in my life but I put him off for 2 months b/c of my weight gain. (I use to be a size 2, now i'm a size 10)
Guess what, I saw him & he still wanted me, for me. I lost 15 lbs since I saw him & he told me as long as i'm happy with it.
We are all different shapes, colors & sizes. don't compare yourself to models, actresses, media, etc. b/c that's not real.
You & your husband are real & he loves you unconditionally. Talk to him & let him know the changes you are going through & you're unhappy with yourself.
It's not going to change the way he feels about you sweetie.
