When to throw in the towel?

I’m 31 weeks and just recently started staying home with our 3-year old. Getting hammered with snow already so probably won’t be getting her outside to burn energy until next week. At what point is it Ok to throw in the towel and stop trying to accomplish it all? I am so over trying to put together dinner every night. Our house is clean, finances taken care of and our daughter is happy but I just do not care about pulling together dinner every night. At this point in pregnancy can I just say f*ck it and let me husband fend for himself?
