Just need some relationship advice

*DISCLAIMER THIS WILL BE LONG*

I met this boy about 3 years ago and had been friends since. April of last year was when me and him made it official. He lived close to me and we’d see each other a lot. He ended up moving to another state a couple months after. We still dated, just long distance-ly. It was fine, especially because I knew he will move back as soon as he finishes school over there. He is also getting his license and will be able to drive. January is when things started to change. He became a little distant and wouldn’t text me or call everyday like he usually did. He wouldn’t tell me what he was doing most of the time. He always seemed super busy. I used to speak to him about this and he always claimed he was busy and will try to call and text more. He kept making these promises but nothing changed. I got tired and ended it. We didn’t talk for about a month, then I decided to text him and tell him that I missed him. He felt the same way so we started to talk again. Then, again we just stopped talking. We hadn’t spoken since until about last night. He text me telling me about how he wasn’t over us and wanted to make it work some how. I don’t know what to make of this. I don’t know if we should try again. He was my first love, and still is. I just don’t want the same thing to start again. I don’t know where my feelings are. I was surprised that he hadn’t moved on especially after all this time. I always dreamed of us sharing a life together. I don’t know if this is a sign that we’re meant to be or not. Should I talk to him? Should we start over and see what happens? Any advice would be greatly appreciated ❤️ thank you for taking the time to read this!!
