I [24F] just broke up with my boyfriend [24] who I live with. It hurts so much, how do I get through this?

My bf been together for almost 4 years, 1.5 of which were long distance. Once I graduated and saved up enough money, he let me move to be with him. I moved a year ago and I've felt as though I was treading water for most of that time. I still don't have a full-time job (or one that makes me happy), I have zero friends or support system outside of our housemates, and I feel like my bf and I enable each other's laziness. I love him so much but we're very different people. As an introvert, his ideal is sitting at home watching TV. I enjoy that sometimes, but I need to socialize. But bc I was terrified in a totally new (kinda lame) place, bc i dont have a car, and bc he didn't want to go out and do things during the week, I never joined any clubs or activities. My PT retail job is the only way I get out of the house solo. Like I said, we enable each other's laziness. He is my comfort zone. I love that zone and want to stay, but it doesn't promote growth (which I need). And life doesn't let you stay in your comfort zone. I even stopped doing job apps a while back because I don't feel like I can survive or thrive in this place. So I want to move out and move back home. But he is one of the sweetest, kindest, most caring people I have ever met. He picks me up from work sometimes so I don't have to walk home in the rain. When I work late, I come home to him making me dinner. We've never actually fought (the closest was us arguing over who would make dinner), partly bc he sees most problems as too small to be worth fighting over. He is so patient with my ADD and with me. He abhors cheating. He loves me with all his heart and tells me and shows it every day. But I still see him as an overgrown child, not an adult. And I need to feel like I can breathe and learn to be independent, which is so hard with him there. I love him so much, but I haven't been happy with my life in a long time. But this breakup hurts so much. And we live together. The pain that we are both going through is causing me to second-guess the breakup. Do I stay or do I go?

TLDR; just broke up with my awesome boyfriend but I still love him & I'm moving home bc I'm unhappy
