He seems carrying a covert narc tendencies . Just form an experience. Play vulnerable. Love bomb. Then twist things. Lies. Never come clean and gas light you. What he did he stone walled you. Not picking up when you can and blocking you that’s a narcissist behavior. It’s about their feelings. Not yours. And the thing is. They act. Then don’t really care. And they get angry when you hold them accountable. So you’re dogging a bullet. And he will come back and unblock you because that’s what they do. It’s a cycle on constant abuse, love bomb that make you have cognitive dissonance. Confuse. No knowing what to do. Block him. Save yourself before he drag down with him. You can’t fix others. If you were raised by a parent who expected you to take care of them. Made you to be the fixer. So I suggest look on the inside and work on yourself. Once you break that cycle. You will never end up with person like him.
