I'll keep it short: My husband's antics enrage me to the point that it affects other parts of my life. Please humor me for a short recap of this week's debacle: Our son was sick a few nights ago, so I asked my husband to take him to urgent care while I stayed home with our daughter and take care of laundry. He looked at me like a deer in headlights and asked where the urgent care was. I texted him a link to the place on Apple Maps, so all he had to do was click on the text for navigation. Once they were at urgent care, he texted me asking for a bunch of stuff related to our son–SSN, name of the medication he takes for ADHD, etc., and the icing on the cake was that my dear husband gave the urgent care the name of a pharmacy that was already closed for the day instead of one that's open 24 hours. He somehow got confused about that and went to the 24-hour pharmacy after urgent care, waited about an hour (with our very sick son), and then got upset that our son's prescription never got filled because they never received it. Our poor son had to wait 12 hours to start his antibiotic since the Rx was sent to the other pharmacy that didn't open until the next morning. Oh, and he also deflected all responsibility for his helplessness and pharmacy mistake and claimed "the urgent care screwed him". These types of shenanigans happen REGULARLY with my husband, and it's super annoying and rage-inducing to the point that I constantly feel stressed and on edge. The worst part is the kids notice it, and our 11-year-old asks from time to time, "Why can't dad be normal?" Of course, I could divorce him, but I don't trust that he'll do a good job taking care of the kids because he constantly acts helpless/clueless. Additionally, I'm often forced to take on the role of referee/peacekeeper for arguments he has with our elementary-aged daughter, which is a terrible dynamic in and of itself.
