I feel like you have many inconsistencies with your train of thought... You say that you "have never been closer to a girl," and that you "feel like" you love her... yet you say that you would probably end up cheating on her? You even talk about potential marriage, but you are willing to end it just because you are going 40 minutes away (which is an easy commute, in my opinion). My personal stance, and take it for what it is:
If you have doubts, then the relationship is not worth it. If you really have so many insecurities about the relationship, then it is pretty much already over. I would say take the beach option ASAP. You should not have to feel trapped in a relationship; it is not fair for you, and it is not fair for her. Be free. Let her be free. You will easily, EASILY find another girl that could be just as important to you, if not more so. It may seem hard, but just remember, the grass is always greener. It may seem like a harder life no matter what choice you make. If she was really worth it, then you would not even have needed this thread, you would have already made up your mind to stay with her.
Best of luck, man. Hope you make the right decision.
