You didn't want to break up with Damian, it was more of a in the moment kinda situation. You'd argued about something dumb, or dumb to you atleast, and then you told him to leave you alone but you didn't truly want that.

around midnight, you hear noises against your bedroom window. Upon checking, you see Damian standing on the fire escape next to your window; in the pouring rain, holding some rocks from the alley under in his palm

"i'm in love with you!" He said, soaked with rain.
