Thanks for your comments.
I understand it is okay to look. I do too. A glance is okay. I don't say he stares not stop. He just keeps looking over at the person, even if they are not in his line of vision. Meaning he has to turn his head. Yes it feels so disrespectful.
I guess I wouldn't feel so insecure if we had a better relationship. Now he is into sleeping on the couch. We don't even sleep in the same bed anymore. Life sucks.
I see why you have the handle you have. If he is sleeping on the couch today either he has serious sleep problems or more likely, serious marriage problems. I don't envy you.
I'm male, I notice every woman out of the corner of my eye, using the same part of my brain that recently noticed when a 4 year old darted into the street from behind a bush, I stopped my car before I realized he was there.
I look but don't stare at attractive women, unless they are walking on a beach, wiggling, wearing about 2 square inches of fabric, wanting to attract (fe)male eyes, there were a few in Puerto Rico last January, going a 1/4+ mile in each direction, several times.
If I looked half as good as them, I'd walk at least a mile a day until I had invitations for drinks, dinner and more, that kind of beauty and power has to go to one's head.
However, your husband is over doing girl watching, while you find this very problematic, I think you need to start giving him a poke in the ribs or a kick in the shins, or higher.
This seems to be only one of several marital issues, good luck.
