There are plenty of opportunities for positive interactions - the ones he initiates. So talk to him if he calls - sometimes. See him if he invites you to do something - sometimes. I think the problem comes in when there is a small to forward by the WAS and the LBS tries to take that inch and make it a mile. You can still have good interactions with him - let him initiate and keep it fairly short.
Plus, if I recall you have kids, right? That should provide opportunities to have positive interactions too, right?
