An obsessive controller in relationships with excessive need for control

Will select people who are willing to be controlled

As long as you don't show your attitude towards certain matters,
Yield, avoid showing your boundary principles,
And rationalize your thinking slide,

Then he will enter the comfort zone:
"You're different from others,
Others don't accept my control, but you do."

So he will treasure it like a rare gem,
And intensify his efforts to lock you down, maintaining this comfort zone

Because after losing you, he’s likely to be disadvantaged elsewhere
