Should I wait or cut off ties na agad?

Problem/Goal: Need your advice if I should wait for him to explain what happened or cut off ties/contact na agad?

Context: He(29) has been busy for a while now, I might say for a week na. I (24 F) was aware naman na he is busy some things sa life but we have no response from the last 3 days. We’re LDR and a situationship. No label at all. We’ve been talking for almost 5 months na.

Previous Attempts: At the first of our convo I said na I want communication like you’ll update me when you’re busy and not leaving me guessing. I tried not to bombard him with msg and calls.
