First of all, if anyone compliments on your good looks, good for you!!! That means you are taking care of yourself and it shows!
I agree with may- I don’t think WASs are always calculating like that. Personally. I think phrases like “leaving breadcrumbs” and “cake eating” give too much emphasis on what you presume the WAS is thinking.
As women, we all have different attitudes on how to respond to a man’s comment on our looks. It could be taken as harassment or a compliment. The response might also change depending on whether it’s from a friend, family member, coworker, or a stranger.
Granted, WAH/WH is a special label that might be confusing to you as to how to respond, but maybe try to think about what else do you see him as? A friend? Family? Stranger? Alien?
My H has commented on my looks positively after BD also. I said “thanks!” and that was the end of that conversation.
