Wow! I agree with SRT about the fireworks. I would only do this if you see it as your last resort. Is there anything else you can do DB wise right now? Also, will the A ending by force bring anything to the sitch right now? Will she view your actions as "manly" or resent the hell out of you for it? As SRT says, it's your call. I've often wondered about writing something to my W's OW mainly because I don't believe she is malicious but in many ways is a victim too. BUT would that make my W want to work out a R with me? Don't think so. So I would ask, do you honestly believe that in his heart your cousin is a good person? Would he actually ponder what you've written? If so, then it stands a chance if not then don't bother. But as always these are just my thoughts.
