Semi-Romantic Reconciliation Help

Salutations! I’ve had a guy friend in my life for about a semester now. We are a year apart and from the same place. He’s been attracted to me since we met and we tend towards being intimate, but I see him more as a beau or sweet friend than a boyfriend. On Monday of last week, we had a spat. I do feel I am in the wrong and that I pushed him too far out of frustration that I should’ve controlled. I shouldn’t have let myself stoop that low and been more understanding- I’ve never seen him so upset. I would like to apologize and rectify the situation, but he won’t hear me out. I tried to visit him, but he won’t answer so I’m giving him space. Any ideas on how I could healthis rift I’ve created? Thank you, in advance!
