My mistake then. That's what I understood from your post.
There's almost no way of confronting him without making him defensive and perhaps verbally abusive. If you're up for it, then go ahead and confront him. You already know he's being unfaithful, and have agreed to separate. Until you're separated, there really is no 'rules' around his infidelity.
I feel the respect was gone the moment you cheated on him the first time. I don't think he really felt much respect for you after that judging by the numerous affairs that he's had and the fact that you stayed with him.
The advice remains the same: Pull away from him for your own sanity and to also not allow him to disrespect you anymore. He should not know anything about your feelings from now on. He should receive no positive feelings from you. No love, no affection, nothing. He doesn't think he needs it. Let yourself find out if he really doesn't by depriving him of all that.
