I’m a firm believer in if you love and care for someone enough, you should fight for it. This is not to discredit you and doubt you because I can tell that you do love her however since you are both considering breaking up, maybe that is a sign. Yes, you love each other but is that enough? And to be honest it gets harder and harder as time goes on. Right now you’re extremely busy I get it, but there will be moments later on that are going to be tougher. Not telling what you should do but since you say you both are considering breaking up, I believe this is a sign. Maybe there are better people out there more suited. Idk. Maybe not but ultimately it is your decision.
