Me [24M] and my boyfriend [26M] had a fight today and the way he's dealing with our relationship worries me. How do I move forward?

Me and my man had a fight, I was willing to talk, communicate and adjust if needs to, because it's been 6 years since we got together and obviously he, and our relationship is important to me. I won't lie, things became a little stagnant between us because I have uni and so does he, but he said "it's not like things are any different if you're here or not"

Before, he too would like to talk and work things out, now he just.. let's it be, as if he's letting things run through the course and if it ends it ends. It breaks my heart tbh.

I know i need to talk to him about it, i know we guys need to have a serious discussion again. I'm just venting, or idk looking for some perspective I suppose. We're good again, but I'm questioning if today's fight is because of his bad mood or because he's genuinely giving up.
