His communication is starting to bug me?

I’m aware him and I are not exclusive, however if you’re interested in that person like we are with each other and are to plan a hangout for a third time next week (long distance) wouldn’t you want to talk to that person? Atleast like 1-2x a day? We’ve been talking since mid April. I feel I’m the one doing the reaching out like 50+% of the time. He will text me either like every few days, or we’ll FaceTime maybe 2-3x a month or sometimes he won’t reach out and just will send me a thing on instagram…I don’t view that as a form of communication. I’m just afraid to ask for better communication since we’re not an item, but when someone communicates consistently, not constantly, it’s a sense of reassurance for me that they’re interested. Thoughts? I get he has a busy career as a pilot but also has down time, and I know I’m a pretty anxious person and so my brain automatically assumes the black and white thinking “if they wanted to they would” so I’m already assuming he doesn’t like me since I don’t hear from him for a few days in a row, and when I do, it’s sometime later at night, like after 8, and no it’s not booty call or sexual stuff. We both agreed last hangout which was over a week ago, we’re looking to settle down and get married as we both hate the dating pool. So I’m hoping that the next hangout (fingers crossed) him and I have a healthy talk where this is going and maybe be an item? I should mention that when we do hang out or talk via FaceTime there’s never a dull moment and we’re so excited to see each other and everything’s great, it’s just during the between times it feels weird.
