I've tried for 4-5 years for that, he backs off when I put the heat on, then comes back after it settles down. Time to change strategy, the best defense is a good offense. Keep at him until he takes the first reasonable offer to get away from me... I need to rock his world so hard that he will stay away from me for good...
I tried the passive approach, it doesn't work with him. Now I have to go with the aggressive approach to drive him out of town...
He hasn't learned to leave me alone yet, but he will....
