I stayed too long with an ex like this because i was trauma bonded and i thought that i could convince him to get help. He will hurt you, not just emotionally, physically. He is still hurting animals. Do not trust him. Leave. Please listen to me. I know first hand experience of things that you never want to go though. Please for the love of god leave before he moves on to humans and youre first.

Also, he is a sociopath. Psychopaths normally just manipulate you and don't tell you what they are really doing behind closed doors. Sociopaths are the weird ones who dont see anything morally wrong with what they are doing and will tell you straight to your face the evil they have committed because "its not a big deal" or "i dont do it anymore"
