Help ladies

Long story short I moved in with my boyfriend kind of quick a little over a month ago.he basically begged and I know it would make him happy ,I knew he was in love and the way he treated me was amazing. His literal words it felt like heaven with me. I wanted this too but it is so scary picking up your life and giving up so much to be with someone, new job, make new friends, meet his family and friends, bond with his daughter etc.. I was there only a week and randomly got a gut feeling and wanted to leave. Like move out ,I wanted to stay together but he broke up with me. I know I was wrong for how I went about it and I have had weeks to reflect and I regret the choice so much. It's been a month already and I only remember him saying he doesnt love me anymore and wants to break up all because I wanted to leave. Everything happened so fast, he didnt even want to talk or try to de escalate the situation he started packing my things for me actually. I think it couldve worked and I wouldve stayed if we couldve talked and made me feel better about everything. We have had no contact for 3 weeks now and I'm still just wanting him back in my life but he doesnt want anything with me at all. How did he go from loving me to literally zero contact over a misunderstanding. What do I do
