Mine used to being forgotten, and learned to just not respond. Mine think by sending anything you validate his belief that you are under his control. If there is any response, just ignore it. Some will hurt you, even when "apologizing".
Those kind of disappointments have taught me a degree of self reliance, and also forced me to seek out people who are reliable.
This behavior isn't universal, just over-represented.
Take care, Mine can only tell you things won't be this way forever.
My dad is very narcissistic and it's his way, or no way. We were controlled our whole lives "Where are you going, what time will you be back" etc. My brother had his GF over for a week (he lives in my parents basement) and my dad was trying to get them to do things with him, but only the things he wanted to do. My brothers GF doesn't like my dad. Not very many people do and I can't blame them
