M, dont try to understand crazy...that just gives you a headache.

Im sorry he's crazy. Sorry you have to have surgery. Sorry your son has to know this about his father.

It isnt right. At all.

I wouldnt keep going on about son's feelings. Not really your responsibility. You explained. If it isnt good enough for him, lLet him call his son and discuss it. If your son doesnt want to....not your problem.

Take care of you, my friend. You matter.
