marriage?

i got engaged a few weeks ago in miami to my boyfriend of almost 2 years. My parents never approved, we secretly dated for almost the entire relationship. We have had our best times but i feel like i made the wrong choice saying yes. He’s super controlling, about where i go and what i wear. I cant talk or even look at a guy, even just a guy friend or a work buddy. He’s emotionally abusive to me constantly and i lost my relationship with my family, mostly my dad when i turned 18 and moved in with him after my parents found out we had been together. But i have found it so so hard to ever actually leave him no matter how toxic and bad things get for me. i am planning to move to miami with my mom and my family there next month, and he says he wants to come down shortly after i make the first move down. but i just feel like this is my chance to get away from this toxic for good? what do i do.
