How to succeed in a LDR? 🛫

My boyfriend and I have only been official for almost 3 months. However, it’s gotten a little repetitive. We were talking for 7 months before he asked me out and everything was going good. Now our texts are the same old thing & when we FaceTime, we run out of things to talk about. He lives a 12-hour drive away (1 hours flight) and I’ve seen him 3 times this year but it’s so hard to communicate when we’re both busy and don’t know when the next time we’re going to see each other is. Advice is much appreciated pls & thank u 🤗
