A romance with a person like this is impossible. They don't see you as a human. They just see you as a tool for their "narcissistic supply." They live in a fantasy world where they are the smartest, most important person in the world, and if you are under their control, they will force you to live in this fantasy world with them and gaslight you and torture you and punish you anytime you try to go back to reality. This fantasy world is their coping mechanism, and you and your feelings don't matter. Your life and your happiness and your mental/physical/emotional needs do not matter. You are just a tool to help keep the fantasy going. If you dare to say "But what about me?" they will call you a selfish asshole and run around complaining to the whole world about you and lie and do a smear campaign to destroy you. Because not only do they not love you or care about you, you mean so little to them, that they would actually enjoy getting the chance to destroy you. It would give them the feeling of power.

And LGB who instinctively get red flag feelings about people like this are gaslit and told they are horrible transphobes for not giving trans people a chance at love uwu. I'm not saying all trans people are narcissistic sociopaths, they aren't. But when an LGB person feels that red flag, whether it end up being true or not, the LGB person should be told to trust their gut and not date that person. But our society suckled on the teat of Rape Culture, so we can't have nice things, like autonomy over who we want to date.
