Do not get stuck in the same loop with people who have proven that they are not the right choice for you. Do not forgive mistakes that you've already forgiven in the past. Mistakes you've watched them repeat once again, without stopping to think of how much pain they put you through every single time. Do not accommodate them in your life, if you know well enough that all they will do is turn everything upside down. Do not tolerate the way they've gotten used to treating you. End it now. End this toxic cycle of accepting them back into your life, only to realize each time why you walked away from them in the first place.
