I am so sorry CMM acted like a child about the phone calls. He doesn't understand what it takes to be a mother. You are a mother and are on call 24/7 when you have children and yes, your son had an emergency and needed your help. I hope the rest of the trip went okay.

OCD or not, his behavior was uncalled for and it's good you called him out on it. He appears to want you all to himself when you are away on vacation, but things happen and you can't give him "all" of the attention. Things do crop up.

Again, I am so sorry he ruined the evening.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
