Help me answer this

So most women are average. They have flaws. Like me. I would say I am below average on looks. I am almost 30 years old. I am 30 LBS over weight (just lost 20 LBS), no butt, have acne, had two kids and have saggy breasts and enough extra skin to make another human. I have a heart condition that causes me to be seated most of the day. My husband says I'm beautiful but he has an obsession with the fit women with nice butts and breasts and are in early 20's. He cant help but to stare in public and he loves watching those work out girls on Instagram (people call them workout porn) I look nothing like those girls and they are beautiful to him. They obviously capture his attention. So how am I beautiful compared to them? I am down right unattractive compared to them. How can I capture his attention like that? He used to stare at me like I was the worlds most sexiest person but ever since I became ill he seems to have lost interest in me. He started looking at other women and doesn't really make me feel special anymore.
