My advice would be to do the opposite of what you've BEEN doing, because that's not working. Trying to "win back a cheating spouse" RARELY works, and what do you have to show for it? He's cake-eating, disrespecting you AND giving you an STD!
A voice-activated recorder hidden under the front seat of his car, and/or a GPS-enabled prepaid phone hidden in his trunk, ought to give you everything you'd need to kick him to the curb on YOUR terms.
Let me ask you something. When he cheated on you eight years ago, what were your boundaries (if any) for him coming home?
