Feeling resentful of my husband today on my brothers wedding day

My husband and I have been together over 10 years. We have a toddler and I’m 7 months pregnant with our second child. I bend over backwards for him and our family especially since I gave up my full time job to raise our family, care for our home and work from home. (I run two very small businesses out of our house that provide a small income). I take care of everything, yard work, vacuuming, cooking, cleaning, organizing, home improvement projects (we have a lot as we prepare for the new baby) take care of our three cats, watch my toddler all day every day, I fold his laundry and put it away for him, hang up his work shirts, buy food he likes when I’m out grocery shopping, cook food he likes, help him foster a healthy relationship with our son (our son prefers me since I’m home with him all the time and my husband has struggled with this), I support his hobbies which are a huge inconvenience to me (he is into buying collectibles for resale but I end up being the one who has to re-sell and do all the work or we just end up with a hoard, he plays dnd 3x a week and he doesn’t help with our son or chores on those days and likes to stream 1-2x per week with his friends and also doesn’t help me on those days). I ask for so little in return. I hardly ask him to do any chores beyond dishes, flipping the laundry, or picking up my sons playroom occasionally. I ask him to pick up after himself but he hardly does. He hasn’t lifted a finger to help me get ready for the new baby. I bought him a book about being a birth partner for unmedicated birth and asked him to read it and he hasn’t touched it. He doesn’t give me any money to spend on stuff I want (which is basically just stuff for our house) and yet magic cards/ deck boxes and other toys are always showing up at the house. I only have the money I make from the businesses I manage and it only enough to get groceries and small things to move along the home improvement projects I’ve been tirelessly working on. This weekend, my brother AND my best friend are getting married. Two separate weddings on a Saturday and Sunday. I’m 7 months pregnant and exhausted. I have worked tirelessly to attend all events related to these wedding s and come up with the thousands of dollars needed for dresses, hair, make up, nails, gifts, the works. My husband wakes me up last Thursday to tell me he has covid. I know this part isn’t his fault but the end result is that I’m going to my brothers wedding alone and I won’t be able to attend my best friends wedding at all plus I had to arrange other plans for my son AND take care of my very sick husband. Like I get it. The covid isn’t his fault but the resentment from all the other times he’s let me down is flooding in and I just feel angry. I’m tired of feeling like I have a burdensome room mate who doesn’t care enough.

Edit: I forgot to mention that another reason why I’m so upset it that it seems like he doesn’t even care that he’s missing the wedding. I asked him today if he was feeling up to showing up to the ceremony and one family pic and he said “as of right now, no” and I just said “okay” and he said absolutely nothing else. All day. Like he is probably sleeping but I feel like he could have said something. Like that he was sorry he was missing it or that he felt it was the right thing to do to stay home or like literally anything. He just appears not to care at all and I’ve been nothing but helpful to him while he’s feeling so awful on a weekend that supposed to be really special for my family.
