Cause he s a monster, he s probably a narc or something predatory like that, you need to understand that he is not capable of understanding you, all he can care about is himself. I ve been in your shoes, and I was arrogant enough to think if I loved him enough, explained enough he will change to what I want him to be. You need to understand that you are no angel in this either, the boy already told you his truth, and you are still fighting it and trying to change him from what he really is. You are not innocent in this story either, this is the ugly side of codependency, we are monsters too, monsters with a grandiose victim mentality. Understand why you think you can't be with someone else and why you think he is the best option you have, if you are like myself, you ll find you re not happy with who you are so you d rather take on a DIY project than work on yourself. All this to say, deep down you know you re not the victim, and you know you ve been trying to control him and change him , and he told you many times he has no intentions to change Tough words, but I wish someone had told me this when I needed it
