I don’t think wanting to see a romantic partner more often than every two years makes one demanding and controlling. In two years one can date, get engaged, marry and have a child. It’s a very long time. It’s not unreasonable expectation to move relationship forward or stop it if nothing happens in two years. And you being afraid your family don’t let you come back I you see her or you having bad family life is good enough reason to end it. How long should she be waiting. She’s not your wife or your family. Who can demand from a girlfriend to wait around for two years? It’s unreasonable
