We are told to love people unconditionally, but sometimes we must get rid of people unconditionally. Some people just keep slithering and oozing in through the cracks in your resolve; they refuse to respect your boundaries. No more mixed messages. You must learn how to close a door permanently. Cut, cauterize and never give them another thought. Monstrous sociopath-like disengagement is your right. Your life is worth more. Don't waste another minute. Let them say you are awful. Block, ban, delete and disconnect. Do whatever you must to take care of yourself and don't you dare ever feel guilty.
