Confused and unhappy

Need help here.... I've been seeing this girl for 7months now. We have the same mutual feelings. We sleep together,do things together,hang out , and I live 36 min away. So we drive to each other often. She is not wanting to commit bc she will be moving in 6 months due to dream job and finishing college. Although idk why but i like label it makes me feel secure. Yes I know that's dumb and she doesnt wanna label us. Even though we are basically doing everything dating couples do. I was going to move closer to her but my nephew whom I am raising due to my sister's death. He cannot do homeschooling in his school district due to school not offering it. He only has 4 months left of this school year. Should we just finish out the school year living at my current place and make it work. I don't see him as often as I would like bc after school he goes to his grandparents and when I get off work it's late. So time for food and bed when we get home. I know summer is coming soon so itll get better. But this girl I've been seeing I really really like her but it's hard to drive so far just for her to spend the night with me. Especially when she isn't able to drive she always wants to be with me. Should I just suck it up and keep seeing her? Which means if I wanna see her I gotta drive to get her and to bring her to me? Or should I move closer to her and drive to take my nephew to school? I am currently living on family property but my dad is a butt. He always brings up me not paying rent so it's annoying af. Im really unhappy all around. Please input any advice possible.
