He doesn't care, and you shouldn't try to make him.
I know a guy like that. He has a girlfriend be when she's not around, it's like he's single. I've seen him hook up right in front of me. It was as natural to him as eating breakfast. When he came back home he probably didn't ACT like normal. To him everything WAS normal.
I like him as a guy friend, but he sure makes a shitty boyfriend.
Don't waste your time trying to make guys like that care.

He's not going to feel bad about it.
He's continuing to pursue these women in hopes of a sexual relationship... he doesn't care.
If he did... he would have
A) Never done it in the first place
B) Did it one time and then immediately confess to you that he made a big mistake.
Someone that does the same things over and over again isn't sorry.
Especially, someone who flips the script in hopes of never getting caught.
When you bring this to the table... he will only feel sorry because you have proof now.
You deserve better and should leave!
People only give you... what you allow.
