It sounds like you found a first rate narcissist. His being overly critical and manipulative and then blaming you and siting his friends opinions that you are the reasons things went downhill are classic signs. He ticks off most of the boxes here. Narcissists do not change because the personality itself doesn’t allow them to even see the need to change. Nothing is ever their fault, so why should they? For your own sanity, move on and find someone who has the capacity to be in a relationship with you. Best of luck!
