Yesterday EX had DD from 10AM-5:00PM (was only supposed to be till 2 but I let her stay longer since I was visiting with SO's family. Anyway! He called me before he was supposed to bring DD back and asked if he could keep her till Tuesday, and threw a shitfit when I said no. It was so ridiculous and it took a lot to not let it ruin the rest of my day.
Also, his visitations are supposed to be on weekends, but I have been letting him take DD during the week because he always has to work during the weekend. I am sick of being nice and flexible, especially when he acts like a jerk if he doesn't get his way.
