SIL left abusive cousin, who I am NC with due to his abuse towards me and my extended family once they separated (basically had kept his psycho personality hidden until then). She is now getting married again and I have been invited to her (small) wedding. I am genuinely really happy for her, do I go or is this disloyal to my cousin who I no longer have (or want) anything to do with? It feel a bit weird, as before all this happened I was very close to my cousin and I feel sorry for him that he's basically ruined his life.
