Few things are harder than seeing the beloved, or former beloved one, commit all the sins they once said to have escaped from.
It hurts in such a particular way to realize, that the shelter your skin provided was so temporary, that the same steps are being followed again. Over and over, outside from whatever you thought you had built.
What a weak stinging pain to be disappointed by the past.
Such bad news to realize this new you is exactly the same as the old one, the one I never met.
