I (32 F) am a first time stay at home mom of an 8 month old. My husband (male 34 M) makes me feel like I can’t complain about bad days

My husband is an attorney and he works incredibly nude. It’s currently his busiest season and he’s been working 14-16 hour days. I do what I can to support him – making sure he has a decent lunch and dinner and taking full responsibility of our son from when he wakes up to when he goes to bed at night. Our son is at an age where I cannot be out of his eyesight without a meltdown. I cannot go to the bathroom, run to another room to grab something or sometimes even turn my gaze away from him without a meltdown. He’s also teething so he’s been pretty much only doing contact naps. He’s 8 months old, not at an age where he can regulate or control any of this. The last several days he has spent the majority of the day whining, crying, screaming or being held by me. On top of that the baby and I have both been sick on and off for 3 weeks.My husbands entire family (parents and 4 siblings + their spouses and kids) are coming to visit – Thursday through Sunday. I have not been able to get anything done without hearing crying. I’ve put him in his bouncer while I’m cleaning or doing something but he just cries. I try to push through but it’s very hot to listen to all day and my patience has been running thin. Yesterday was especially difficult. I spent half the day crying myself because I was just so frustrated and overwhelmed by the constant stimulation. I texted my husband to let him know I was having a really difficult day and was super overwhelmed. I told him I didn’t need anything but I wanted him to know my state of mind when he got home so he didn’t think my mood was directed at him. I told him I would probably sit in silence or watch a movie with wine that night to just decompress. I never text him while he’s at work but I was really struggling and knew an argument would likely happen if I snapped at him after he was home.He did not take it well. He responded by saying how dare I pile more onto him. He told me if I was looking for something extra from him that it wasn’t happening and if I wasn’t I was just hijacking and wasting his time. I felt really hurt by this response and we didn’t speak until this morning when he told me he wouldn’t be speaking to me until I apologized for the “bullshit” I pulled. We then argued and he told me I was entitled and out of touch with reality. He told me I should consider getting a job because he’s over our “arrangement” if I can’t get through a bad day without burdening him with it.I feel like I deserve to be supported even when he’s having a naked time at work but maybe I’m totally in the wrong? He will not back down and says I’m delusional if I think I’m in any way right in this. I honestly feel crazy like a made a big deal out of nothing? Today was just as hot and I felt like I have no one to turn to because I can’t burden my husband. How do I handle this moving forward or reframe my point of view?
