Moving on is not that you have to completely forget about him/her. Sometimes you just have to move on because you know deep down they can actually live without you. And sooner, you will have to because life is in motion. You move on and live your life as well. You don't give up on someone you love. You just don't. You just let them live their life without having you being an important part of it. I'm not saying it's easy, but I'm not saying it's hard either. You just gotta find the purpose of living on your own, not by having someone by your side around the clock. Just by being you. "You don't stop loving just because someone walked away from your life. It's like you stop breathing just because you got cut."
