Leaving the marriage

Hey ladies! I need advice or I guess I just need to vent. But anyways, this morning I have spoken to my husband and told him that I want to be on my own. We’ve been married almost 4 years and our marriage has only gotten us no where. It’s the same things over and over again with us. He has mentally and emotional abused me and I gave him so many chances/forgiveness in the past 2 and a half years. This year I’m just like on autopilot. But I have had enough. And I want to be happy, stress free, depression free, anxiety free, high blood pressure free and I just want to feel and be free. I want to better myself. So I took the time to end things. I am currently still at the apartment with him I’m just sleeping in the other room. I am looking for an apartment but I guess my question is how do I do it? I’ve never been on my own and I’m scared. Or nervous maybe. I don’t know if I did the right thing. I’m stressing alittle bit. But not as much as I was before I ended things. I feel fine right now but it’s so awkward being with him at the apartment I don’t know what to do
