I know this would be annoying but try not to let your husband know that it is hurting you - maybe he is doing this to get a reaction from you, do you think?
So, maybe you could say something like this,
"oh, yes, she does have a nice face or hairstyle, or whatever".
Don't let him see that it is hurting you
OR
alternatively
you could tell him in a nice way that it is hurting you.
Try to use "I' words instead of "You" words.
Say, for example,
"you know honey, I feel pretty sad or hurt when you make comments about other ladies. I know you probably feel they look good, but could you please keep your comments to yourself".
I dont believe in "getting back" but perhaps you could say
when a good looking guy is on the tv,
"Wow, he looks ok"
Just to see your husbands reaction(to prove a point).
I wish you well.
I know of guys that do this to their wives. It's annoying.
It's immature too
good luck, try not to let him get you down.
