Hi Karlee, wow, we have a lot in common! I met my (now) DH when I was studying in London as an undergraduate student, then spent another year and a half in the US finishing my BA. During this time, he was deployed to Afghanistan (he was in the British Army at the time). He returned to the UK, and I moved over for grad school a few months later to study at Oxford. Luckily, he was stationed in Aldershot then, so we were close and saw each other every weekend and whenever he had leave.
I had applied to quite a number of school in the USA, and I was not considering grad school in the UK for a number of reasons. However, one day I was browsing courses in the UK and came across one that I liked at Oxford, applied on whim and was accepted. A lot of people thought I was going to the UK to be near him, but the fact of the matter was, I felt like if I got accepted, I needed to take up the opportunity. I wasn't willing to compromise the quality of my education just to be near him.
I'm so glad that I actually did go to grad school here. I was able to see DH more often and gave us a sense of 'normalcy' in our relationship after having a LDR for so long. And it prepared us for another year and a half of separation, as I moved back to the US for more grad school!
BTW, my DH is from Sheffield! It is a great town for university students, I hope that you enjoy it! Good luck with your course and the future with your BF!
