I'm at home on a Friday Night too. Worked till 7:30 then I was watching "What would you do?" I love that show. Now I'm getting ready for ice cream.
You don't really want to drink and ruin your sober time. It's not going to solve anything and certainly not going to change the people in your life. Only they can change themselves. You worry about you.
My ex was the same way. I let him pick the pick up schedule so it would be convenient for him. Well, something always came up or he was late, etc. We had to start meeting in a public parking lot and I started bringing a 'witness' with me -just in case. So yeah, I understand. But there was nothing I could do and would just man up, do everything the right way and be compromisable. That's all you can do -you can't MAKE them be on time.
I know how stressful it can be. Try to be a positive patty!
Wishing you peace and strength.
