If someone doesn’t care about losing you

Close one door and another (only then) opens; let go of the past in order to embrace the present/future. Let those people go mainly to make space for someone more appropriate and deserving. They are there even if you can’t see them right now. ~ David Wolfaardt 

Never lose yourself while trying to hold on to someone who doesn't care about losing you.

Move on and don’t put energy into wondering “how did this happen” or “why did this happen”! Those questions can be revisited after you begin taking care of yourself and are in a much better place “emotionally. ~ Charles Brown
