I(20M) have been with my GF(20F) for almost 2 years(young immature love). I feel like we’re holding each other back and I don’t know how to communicate this to her without upsetting her, and I don’t want to break things off since she feels like she is my soulmate.

I talked to my GF this morning about future goals and my current mental state. We hang out everyday day wasting away days and enjoying each others company, but looking back at all the time, less could have been spent hanging out and more should’ve been spent studying or going to the gym or doing anything productive. The problem lies in communicating to her about how I feel, changing my routine, spending less time with her and working on myself a little more. When I brought this up, she made it seem like I don’t want to spend time with her anymore and got upset. I’ve been missing classes and been behind in school because of the time we spend together, sometimes it feels like she doesn’t care about or respect my wellbeing and gets upset if something doesn’t go her way. I’m stuck in this loop of productive thought and careless living. I don’t know how to move on and tell her I need more space without telling her- in her words- I want to be away from you. Advice?
