Should I keep the distance from my guy friend?

I havs a guy friend who 90% sure likes me. During summer break he tried to meet up with me but since I felt uncomfortable meeting him one on one outside uni I kept putting it off until we met once and when uni started I kinda distanced myself from him since he had clearly misunderstood my friendship as something more. So recently even though we have very occasional conversation I have noticed that he has almost stopped contacting me (after almost 4 years of nearly constant contact) so my problem right now is, should I try becoming his friend again or keep distancing myself from him? Because I was okay with his friendship until he started acting like it was something more to the point many people around us kept noticing.

P. S. during my distancing phase I never once disrespected him and have always talked to him with a smile so I know he isn't hurt by anything rude.
