Should I stop getting my hopes up

I’ve been hooking up with this guy three times since the end of december. Till about mid January we messaged every day. I went away on holidays for a week and since about Jan 10 I haven’t seen him. He messaged me a few days after I came back and asked if I would want to do a yoga class with him. About a week later we messaged and he asked me to stay over but I said I couldn’t. I thought he got annoyed so I kept my distance. I said we can meet in two days time and he said he’ll let me know because he’s been studying for his exams, he never got back to me. About a week later which is this week. I just messaged “hey, how are you” and he said he’s been busy studying with his exams coming up this week”. We made some flirty jokes and he said I’ll need to go over and I said after exams, focus on them first and he said I know xx.

Should I keep my distance till he is done with his exams if I don’t hear from him then I know where he stands?
