Sounds like you did the right thing. Your husband must be really happy when he can have both you and a girlfriend on the side. When you take away the option of having both then hopefully he'll at least think a little. I'm sure you've done that in the past too and it hasn't changed the outcome but you can keep drilling the point into his head that he can't have both.
It's nice that guys have noticed you when you go out with your work colleagues. It sounds like your husband notices you too, he just isn't playing by the rules. It's hard dealing with someone like that. Is it all just a game to them?
