We need to stay inside

Earlier today my boyfriend was saying he was going to go to his office to pick something up. He later said he may be filming something on Wednesday. All day I’ve said we need to stay inside unless it’s for food. We went out for a quick walk around the neighborhood to get some fresh air and upon returning I suggest tomorrow we slip a note under our elderly downstairs neighbor’s door (who hates and harassed us for some time, yet we recently introduced ourselves and became likes) and offer our help in case he needs anything. My boyfriend immediately started arguing with me, saying that my suggestion goes against what I said all day about staying inside. I said yes there are exceptions, like helping somebody in need. He wanted to find any problem he could with me wanting to offer help. It turned into a huge fight of me calling him a d*ck etc and now I’m pouting in my bedroom about to go to sleep and this is only the beginning hahah
