Boyfriend stationed in Japan

My boyfriend is stationed in Japan for 3-5 years and the decision to move is weighing on my mind. We’ve been through 7 months of distance while he was in Chicago and this is just different because our time apart will be so much longer. It’s not going to scare me away at all, I’m 100% in and I think that’s why I feel the need to move to be with him. I’m going to transfer to State school to obtain a bachelors degree in Biology but I’m miserable and I honestly just want to put it on hold and move. I know it’s not the best idea because I should work on my career, however I am not happy. We’ve talked about marriage and school and he believes I should get my degree then move out but it’s like I’m ready to go now. Is there anyone that has been in a similar situation and how did you make that decision?
