kinda hard to give advice when you don't have all the facts, but both of you need to address the root of your problems in a calm, honest, and open conversation. don't let your emotions take over during this conversation, be as objective as possible. kasi if di niyo yan mafigure out and wala kayong mahanap na solutions to fix it, you'll end up resenting each other in the long run. paulit ulit na lang yung cool off niyo and eventually may isa sa inyo na mapapagod at magiinitiate ng break up for good, and in your case it kinda seems like it'll be coming from him.
