Let me put it to you this way. If you were in your W's shoes and she saw how you messed around on her. How would it sound like hearing that you loved her just when she found someone else?
Better yet, you TOLD her you were through and flaunted the OW in front of her. The ILY would just piss her off.
If you are dead serious about loving her, you'll give her the space she needs to trust you again.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
