My husband (M47) is trying to kick me, (F40) out over my sleep schedule

My husband and i have been married for almost 20 years. We have two kids who are in college, away from home. I have a job where i work nights, usually not getting home until around 4AM. I've been doing this for a while and it has caused me to be a night owl. I sleep in later than most people. Sometimes i don't get up until around 3PM. It doesn't affect work, i always manage to get good sleep before i go in for the night. My husband who works regular hours has always tolerated it.<br><br>In the last year or so, he's started making a bigger deal of it. He wants me to wake up earlier (i won't say specifically what time he wants me to wake up, but its morning) so that we can share time together when he has time off. I've been trying to get to bed earlier, but i'm not ready to upend my sleep schedule that quickly. Sleep is important for my job and i don't want to risk messing that up, as much as i want to accommodate him.<br><br>He's now saying he wants me to move out. Like, in the next month he wants me out of the house we've lived in for 20 years. He says i don't make an effort to spend time with him. I feel like i do, i've started setting alarms and making myself get up, and i power through to spend time with him even if i'm tired. He doesn't seem to recognize it, or he says it doesn't count if i'm tired.<br><br>I don't know what to do. Do i need to just put 20 years behind me and move on with my life? I thought we were happy and as much as he talks about all the things he's done for me and given up for me, it doesn't really feel like it. I feel like i've made sacrifices too, changing my schedule to allow him to do things. Giving up my career so that i could take the night shift and he could change careers for something that paid better. Stuff like that. He doesn't seem to recognize that though. Am i in the wrong for not just totally upending my life and sleep patterns to accommodate him? He doesn't work anymore, so i'm not sure he really has to worry about his sleep schedule.
