think of it as chasdai Hashem. often a person is unsure whether to continue going out with someone or not and ends up dragging it out and second guessing herself. you were unsure but didn’t break it off, and then he did. there is no second guessing-its out of your hands. accept it peacefully from Hashem.
also, if he didn’t the reason to the shadchan its out of the realm of your bechira to learn a lesson from it.
if you were moving towards ending it, be happy its over sooner and out of your hands.
this advice was given to me after my first shidduch that didn’t work out by an older friend who had already been dating for years at that point…hope it helps.
