I'm really sorry that you're struggling right now and I agree with Jacqui_D to take care of yourself.
When I was overweight, my husband used to always want me to "dress sexier" - not lingerie, but with everyday stuff. For him, it wasn't about being provocative, it really was about wearing clothes that fit me and didn't swallow me whole. I was under that (very very false) impression that wearing big clothes would hide my body, when they actually just made me look bigger.
One year, we took a family trip to Costa Rica and I had to purchase a dress and a swimming suit (UGH) and I tried something new - I had him pick them out for me. I didn't feel pretty or sexy
at all in either one of them, but he really liked them and liked how I looked in them!
So, instead of trying to find the "perfect" lingerie, maybe ask him to help you shop and see what he responds to? He may love you in something that you'd never even consider!
