I think she spelled it out for you pretty clearly. She wants to have control of the relationship, and she wants to know that you will never leave her. Incidentally, how does that make you feel? Obviously not very good. And in time, it might just make you feel like very few women would want you. And then she will have accomplished what she wants... . you won't leave because you'll think there is nowhere else to go. Check-mate. You get controlled and used for her purposes until she is done with you.
I received many such condemnations and back-handed compliments. You feel like "uhh... . thanks" but secretly wonder, "Who the

#$ says something like that to someone?" Its a put-down disguised as a compliment. And yes, if she is anything like my ex, she will capitalize on and exploit your insecurities to keep you under her thumb. And you won't even really see that she is doing it until you are in too deep.
They need to have control of the relationship, and they need someone to unload their guilt and shame upon. Your flaws and insecurities are fair game, and they will likely become the focal point of the relationship in due time... . all to keep you constantly thrown off and to keep the eyes on YOU being the flawed one and not on her. That's how they roll.
