<human>: We've been together for our entire time at college and I was recently accepted into a very prestigious graduate program in another state. So, in August, I will be moving to attend another university. My BF still has another year of undergrad left, so he will not be following me. At least not right away. 

We have a very happy relationship. We have fun together, get along great, are very affectionate. He treats me so well. Being together is very easy! He's my best friend. We have talked about long terms plans and marriage. Until very recently, I was sure we would be together for a very long time.

I want to feel excited about my accomplishments and future career. I am about to graduate from college and achieved exactly what I have always wanted to achieve by getting into this particular grad program. But I can't be happy about it for more than 5 minutes before my relationship brings me back to reality. Right now, the plan is for us to be long distance until he graduates, and then maybe he will be able to find a job in the city I will be living in. It sounds totally do-able in theory, after all, it's only one year. However, I can't manage to get over the feeling that it just won't happen. I can't see him graduating and finding a job and moving hundreds of miles to be with me. We talk about our future and it sounds amazing, but I feel like I am the only one of us who is actually moving forward. I love him and I want to be happy with him long term, but I am having a hard time ignoring these ominous feelings. When I think about what it would be like to not be in a relationship anymore and move away and start my professional life on my own, I feel free :/ when I think about being together and him maybe eventually moving to be with me, I feel uneasy. I can't tell if my relationship feels like a burden because we aren't meant to be together or I'm just doubting myself. Should we even try to make long distance work if I am having these feelings?

Can you condense the text into a few key points?
<bot>: I really want my BF of 3.5 years to be "the one," but I can't shake the feeling that maybe we are meant to go our separate ways when I go to grad school in another state next year.
