Am I overthinking?

So , I've been seeing this guy for a few months whom I met on Hinge. It's been going great , we hang out , we vibe , we even went on a trip together (It's been 2 months since we first met ), now he's doing his articleship (CA) and has his 3rd CA paper in a few days and he's been kind of cold like only good morning, good night text and barely 10 minutes call, my heart is saying that he's about to break things up but my brain says that he's just occupied with work and exams and will come back to normal as soon as his work load becomes less and exams get over . Am I overthinking?
