Give him/her a sorry and live card at the same time and, i bet they'll accept ya back and if dont? Just act super nice and sweet towards them and give him everything they want (thats what i do everyday to my classmates TwT) im sorry if it doesnt work mate, goodluck!
@Tordlarssoniscute don't get back with them, there was probably a reason you two broke up. Don't get back with them especially if they dumped you for no reason. They mostly don't like you the way you like them.
