The truth is, when someone doesn’t want you, no reason matters. No amount of fixing could change that and actually, there isn’t anything that needs to be fixed because nothing was wrong or missing in the first place. You have always been wholly you, before or after them, including all the flaws and imperfections that make you unique. So if you ever feel the need to redeem or validate yourself after being rejected, please don’t because no one can take anything away from you by not wanting you and you aren’t born to prove yourself to anyone.
