Try writing first thing in the morning. Write about your dreams or the dream you just had last night. It gets thoughts out of your head and off your chest so you are able to move on.
Don’t expect to have plans every single night. You will not be running around the city bright-eyed and a little tipsy, holding the hand of a cute boy who rides motorcycles every evening. (But sometimes you will).
Mainly, it ended because you knew you were meant to be together but neither of you were ready to settle down. At least, that’s what you tell yourself, but never say out loud. Not ever.
