I will tell him my feelings tomorrow and how wrong I felt that was to attack my wife.
you dont want to respond to an unloading with an unloading.
it will escalate the situation. if you overtly side with your wife, it will isolate your son in law, or depending on how you go about it, it can align the two of them against you if they make up.
you want to be the emotional leader who brings everyone together.

Be caring, but don't overstep. We do not want to let our fears, obligation and guilt to control us or allow us to be manipulated into taking care of another person when it really isn't healthy to do so. Instead of being the rescuer and doing the thinking, taking the lead, doing more than our share, doing more than is asked of us - simply be a supportive, empathetic listener and provide reflection, coaching, and assistance if the person asks and is taking the lead themselves. It is important to recognize the other person as an equal (not one-down) and give the other person the respect of letting them take care of themselves, solve their own problems, and deal with their feelings as they choose. Remember, the rescuer has the most pivotal position on the drama triangle - you are in the strongest position, at least initially, to redirect the dynamic into healthy territory.
what this looks like could mean a number of things.
what is your relationship like with your son in law?
if its good, and close, you are in a good position to reach out to him, listen as a compassionate ear, understand what was going on with him, validate his feelings, and also nudge him in a healthier direction.
if not, it may be best to stay out and allow the two of them to resolve the conflict.
