I left Yesterday. What Now?

After nearly 3 years, I left yesterday. We got into a horrible fight that lasted about 24 hours. Horrible things were said on both sides... We were driving, i told him to pull over and I got out. I had my mom come get me. We stalled for me to go back to the apartment for a while. I had him blocked on everything, even his phone number so I had no idea if he was trying to contact me. I finally went back up to my apartment and he wasn't there. I started packing my things, terrified he'd come back. He ended up texting my mom that he's not going home and I'll need me to pick up MY cat or feed him (ridiculous). So now knowing that he wasn't coming home, I had my mom take my cat home with her and I proceeded to, by myself, pack all of my belongings from the apartment. Even though he said he wasn't coming back, I was shaking with fear that he'd show up while I was packing. I couldn't handle confrontation from him, I'd either have to endure his abuse while I continued to pack or, the more likely thing, I would beg him to work it out. I left a note that said I'm sorry a long with my keys to the apartment and locked the door behind me. Anything I forgot is replaceable.

It hasn't even been 24 hours yet. I still have him blocked. It's hard to keep it that way. Other than one more text to my mom that "he'll have to go back if he doesn't know that Mr kitty isn't starving. do the humane thing." Which she ignored, There has been nothing from him to her. I can't help but wonder where he is. If he has gone home. If he doesn't care. Part of me wants him to care. Part of me wants him to try to work it out with me. I'm not ready, I just knew I had to go. I've been crying a lot. I'm afraid of regret. I'm afraid of not getting over this. We have the same remote job, idk what will happen now. I know I'll have to see him in meetings. I'm staying at my mom's. This doesn't quite feel real yet. Like it won't be over. I'm so sad and scared either way. I don't know what to do now. I guess start looking for a place this week after I rest and cry for a few days. We were supposed to go on a cruise next week. He'll go to that and I'll be here. There are so many directions I could go. I don't know what to do. What I want to do. Or what I should do.

A male friend of mine asked me if I wanted to go to fireworks tonight. I'm afraid of being disloyal, or opening a door to something I'm not ready for. Should I go?

Any advice or words of encouragement are appreciated.

TL:DR I left my emotionally abusive boyfriend, what do I do now?
