Why doesn't he notice or comment on my weight loss?

I have recently lost 40 lbs down from 165 to 125, I am 5'5" tall. I have always worked out and been in decent shape but I am definitely looking and feeling better. I have noticed men checking me out and everyone comments on how good I look, except my husband. All he has said maybe 3 times is you are shrinking. He hasn't been any hornier, just nothing. My question is for the guys- is this odd? And to the gals- what have you experienced with your men in this sitiuation?
