I have a LONG history of "co-dependency issues" and I think my personality is such that I will always have the tendency to go in that direction!
I have, on NUMEROUS occasions asked him to give me advance notice, 24 hours PLEASE. He usually gives it to me BUT ONLY IF I ASK. One new thing I am working on is to give HIM the responsibility of communicating pickup/drop off time (Saturday is usually the only day it is an issue...other times are usually stable). I have a life of my own and 2 other kids I need to plan for! He has agreed that it is not unreasonable to give me 24 hours notice and he has agreed that it is not unreasonable for HIM to take responsibility for communicating that to me. ESPECIALLY since he gets so irritated when I ask him questions. I have never been able to satisfy him. I am ready to stop trying. I am going to focus more on what I want and need.
