[22M] + [21F] | First real relationship. Scared of stability, or decay I won’t admit.

TLDR: I am in my first stable relationship, and I dont know whats normal and what isn’t, and would like clarification from a more level headed person.

Whole Story: Hello! My girlfriend [21F] and I [22M] have been together for 5 years, highschool sweethearts, we’ve always had our moments of needing space and whatnot but we’ve always even in adult life made time for each other, dates, imtimacy, fostering connection, she even learned about video games so she could play them with me (like halo campaign and stuff) and for the last like year and a half I feel we have been drifting apart, I am huge on physical touch and physical affection, just always have been, she has slowly been stepping back from that, and us spending time together as a whole, she works full time as do I, which is fair to say limits our time together especially when we don’t live together. Problem is its not just like we dont spend 6 hours a day together, we say good morning and good night and see each other in person maybe once a month now, and I have a job opportunity in another state, approx 18 hours of drivetime away, she refuses to move, and I mean I get it because she has a job too, and family here and I don’t, but I also don’t want to sacrifice a very very limited opportunity for someone my age to get ahead if the signs of a deteriorating relationship are present and I just cant see it because I’m so stuck on her being my first long term relationship, and my first real love if that makes any sense. I don’t really know what or how to explain it better than that I sat over this for like an hour trying not to make it a text wall, so if you have follow on questions let me know! I can give greater details. Please don’t bully me for my writing, I don’t do this often.
