My aunt was a good friend of Cynthia Lennon, the stories she told about him!!! He was not physically abusive but was very psychologically nasty indeed, just terrible. He took far too much LSD back then, he was never off the evil stuff. It was while he was on this drug that he met Yoko, she stalked him unmercifully until she broke him and he submitted to her. Serves him right one might say? It takes five slugs to kill a Beetle.
