Sometimes you let go of people without even noticing. You stop thinking about them like you used to, it eventually isnt your daily habit anymore. you stop waiting for them to reply to you. you get used to it. you stop allowing them to take up so much space in your life. you move on, you go about your day without worrying about them. you stop expecting them to come back with an apology. and therefore, you finally accept the fact that they are no longer a part of your life anymore, this is you letting go.
