Tips for when partner comes home

Hi, I'm awaiting arrival of my partner (M,40) and I'm filled with dread, simply because I don't know the mood that's going to come through the door but I highly suspect it will be cold/blaming/grabbing his pillow to sleep downstairs (he says being around me makes him feel worse). Any tips for navigating this for nights i cant go out? To distract myself I've tried reading, netflix shows, texting friends, exercise/immersing myself in my own word but I just feel like crap and I'm wondering if there are any mindset tips or other things that have worked to help others. It's the blame/feeling rejected that makes me most anxious I think
