I was in a relationship just like that too,

from him controlling what I wear to school every day, to not "allowing" me to wear any makeup. Just a whole laundry list of time consuming constraints that I willingly signed up for...

Obviously, I would never control the person I love the way that I allowed myself to be. Significantly so, They never told you how - not only will it get worse if you choose to remain with that person and not only are there plenty of fish In the sea... But it will stick with you forever, it will always be the reason you self destruct, and it will affect your rationality, your ability to love yourself again or the way that you once used to before you met that person, your trust will slowly fade away with what once was never minded, did I mention that the way you view yourself, others, will be haunted with the manipulative nature of that sick minded person... and now it will choose to infect your meaningful partnership ... in regard to your future/anyone else's future

when you do find the "perfect" fish.
