Calm down....you basically threatened W which elicited a phone call from FIL. Not surprising at all.
Get your center back and focus on your goals. Be the better person that you are capable of and much more. What needs to happen is for you to cool off for the next 48-72 hours so the dust can settle down.
Taking a scorched Earth approach isn't going to help matters at all. Drop the self-righteous chit. For real. For your own sake.
