Would you stay with your partner if they wanted to move out?

My girlfriend is the bread winner, she’s sat me down and says she loves me and wants to stay together but wants to move into her own studio apartment and save a lot of money for a year. I would just move back to my moms house 20 mins away and she wanted me to work on my finances. All of our arguments have been how she pays for everything and she wants her space to work at home alone. She pays all the bills and I help out when I can. Is it fair to stay in the relationship with her? Is this taking a step back?
