Big feelings make fast decisions. Give it one night before you give it an answer.

Intense emotion narrows what you can see and speeds up what you do, which is useful when something is chasing you and unhelpful almost everywhere else. Under that pressure the urgent option looks obvious, and the same situation looks entirely different once your body settles. Nothing that actually matters gets worse from one night of delay.

Make a rule for yourself about decisions taken while your heart is going: nothing final until tomorrow. Say that you will answer in the morning, which is a complete and reasonable response. If the answer is the same then, you have lost nothing by waiting.
