I feel like just by reading it I understand where you’re coming from but he is trying his best even while he is sick to make you smile and laugh. While you don’t feel good, push past that and just enjoy what your partner is trying to express to you be close and all. After all- he is pushing past how he is feeling to try and make you laugh. I will admit the repetitive jokes can be irritating especially when you just flat out don’t feel good but that is his way of communicating to you that you are probably making him feel small for rejecting him trying to make you laugh. Buuuut all that said- he still shouldn’t make YOU feel small either
