Not sleeping through the night

Does anyone else have issues not sleeping through the night ?? I literally went to bed around 10pm and woke up around 1am. then I can’t fall back asleep till like 6am or so. Usually when I wake up at 1 I go downstairs to eat something because I wake up starving. My husband wakes up like literally no longer than 5 more minutes after I get out of bed; angry because he can’t sleep if I’m not there. He thinks I’m lying to him about ever have fallen asleep at all and says “who sleeps for 3 hours” and just thinks I’ve been up the whole time and gets mad at me. The reason why he thinks that is because he falls asleep before me so he never sees me fall asleep then he wakes up when I’m out of bed and I’m up as well. I just don’t know what to do.
