If their calendar is so busy they can’t find time to go for a walk, Let Them. If they cancel plans this weekend because they’ve had a long week at work, Let Them. If they fall in love, or have a baby, and you are no longer a priority, Let Them. If they move away, and start a different chapter, Let Them. If they stop returning your calls, Let Them. If they are prioritizing other friendships or work, Let Them. If the timing, proximity, or energy is off, Let Them.
