Unsure whether to break up or not

Me (20F) and my boyfriend (22M) have been together for nearly 2 years. However for the past 6 months or so hes been barely interacting with me. We're long distance as hes in the army but even when he goes home (every weekend and a few weeks a year) hes still too far away to travel for a few days. I havent seen him in person for a year but im seeing him in 3 weeks.

The distance isn't the problem, it's hard but manageable. What is the problem is that hes not very good at communicating. Ill send him a text at 8am, he wont respond until 10pm after ive gone to sleep. Hes home for a week, I'll get maybe 2 texts a day if im lucky. He claims it's because hes tired and wants to relax which I get. But all im asking for is just a quick "going out with family, talk later" text.

Also he games with his friends for multiple hours a day when hes home but wont call me for more than an hour, and only ever late at night after I would normally sleep. So i miss out on sleep before work and im tired all the next day because hes called his friends all reasonable hours of the day.

Ive complained about this before and he says he joins the call with his friends then falls asleep but ive seen him streaming his gaming. Ive had to block their group chat because it makes me really upset.

I want to break up but im concerned im being too harsh on him considering the circumstances
