On the weekends my wife and i take turns sleeping in (or doing whatever) until 9am while the other parent watches our 2 YO. Yesterday my wife mentioned she wanted to attend services today and so i would start watching our son at 9. I goofed- i stayed up too late watching sport and slept until 9:20. This meant she did not have time to get ready. I realized that i messed up but i feel like she could have and should have woken me up so that she could get ready. She feels like she should not have to do that and it was my responsibility, and that it shows i don't care about her wishes. She is angry and will likly be angry for the rest of the day. waking me would have made everything work out i think. I know i goofed, but am i being unreasonable to not feel like she should harbor resentment for the rest of the day?
