You took the first and biggest step, which is getting away from the abuser. Distance and time will likely begin the process of making you feel more safe and comfortable. It starts with having a door that the abuser doesn't have access. Physical space helps.

For me, time helped the most.

Abusers are often focused on self-destruction, so it becomes less about what you've done and more about how they've found new targets of abuse or have become targets of abuse themselves. These archetypes lend themselves to cyclical behavior in a sort of cruel irony. I've seen it a lot in my work.
