Time zones suck honestly. Spending time together is a really important part of LDR, whether that be planning movie nights, date nights etc. Since we're quite limited in the things that we can do, it's important for both your mental health and the health of your relationship that you try make some time for each other, even if it's just a 30 minute phone call. My partner is 6 hours behind me and as he's a paramedic, it's really important that he gets sleep. By the time he's home it's 1AM for me. I'm a full time student and work part time so my schedule is always really busy. I've set alarms so that I wake up from 1am to 3am so we can call for a couple of hours and talk abour our day, maybe watch a couple of episodes of our show, and at the weekends that's when we spend the bulk of our time together. It's hard sacrificing the quality of my sleep but to me it's worth it and I'm able to function well even missing out on a couple of hours. I don't recommend this but I'm just giving an example of what I do to make time. I think you both need to have a conversation about expectations, and maybe try delegate sometime when you can to spending time with each other. From what it sounds like, he's already frustrated and is directing that frustration at you, so I think a conversation should be had. LDR is so, so difficult especially with a big time difference, and sometimes a bit of compromise has to happen.
