Does "let someone go" has the same meaning as breaking up with someone?

Yes, it can be interpreted in that way! The singer uses "only know you love her when you let her go" to mean that often, one only realizes they love someone when they break up. It can also mean to release someone from an emotional bond, or to end a relationship (platonic or romantic) with someone. Ex: Although I broke up with my girlfriend a long time ago, it took me years to let her go. Ex: I think you should let him go. You guys aren't good for each other.
