I can't let go of my ex-girlfriend and want to break up with my current girlfriend

Not all separation is due to lack of love, and not all together is due to love. Good love is not measured together. Even if we are separated, if we inadvertently see each other's previous photos and messages at some time, we can smile from the heart, which must be the best commemoration of our past love. I really loved someone, whether together or not, I just hope you are all right.
