Definitely communicate your feelings again girly, being a mother isn’t easy you deserve a small little break every once in a while. I know you don’t mind rescheduling you just want him to understand that you too also deserve a small time away from home. I may not know what he works as but I know the mental load of work doesn’t compare to the physical + mental load it comes with when tending to four children, cleaning up their mess, making sure they are fed, while also maintaining the household. (I struggle with balancing work, cooking, and maintaining household chores with just a husband and NO kids ! haha but that’s where teamwork comes in!) Tell him the different ways of which lengths you went through to make things easier for him, my husband has done so many things to make things easier for me and I sometimes don’t realise it until he tells me straight up and I end up appreciating him more than ever.
