There is no irritant as painful as an ace up your sleeve that you can never use

My brain is a mess right now. How do you explain something to someone who makes it so obvious they just don't care enough to listen?

I'm really struggling with this co-parent business. I am the only parent for 28 nights of the month. I am the only parent for 28 days of the month. I take my darling to nursery, to the park, to activities, shopping, to visit family and friends, I make her 3 meals a day, I make playdoh animals with her, I kiss her ouchies better...I can truthfully say I do everything for her. I would be completely happy if I could up that to 30 days a month.
