<human>: Met my GF 5 months ago, and thinks honestly have been going fantastic. Shes sweet as can be, we have mutual interests, we get along great and rarely ever bicker. This is not my first relationship nor is it hers, and I do realize that this is still a short time of being together. However, lately I seem to just be unsure if we will work out. She lives about 45 minutes-an hour away, and is in school so typically we only get to see each other on weekends or when i drive there during the week. She lives at home, and participates in pageants which take up some weekends. Her parents are wonderful parents, but quite hard on her when it comes down to doing things without them as they are a very tight knit family.

I'm not one who needs constant attention, and the seeing each other only on weekends is fine with me as there really is no choice. But she is from a small town, and so am I, but my goals are to travel. I work in the medical field, and have the opportunity to do so for work. When she graduates next May, I feel like she may not want to leave, despite her never stating that. I have already set back my plans of traveling next month for her, and sometimes I feel like I am just held back because of her situation. I care deeply about the girl and would love for things to work out, but sometimes I feel restricted in my life even though it is out of her control as she is simply going to college. She really does try her best to balance her personal life with me and her family as best as she can, and she does a good job. I would hate to lose her, and I hate that I'm having doubts. I just don't know what to do as I'm completely aware of our situation and I feel I may just be acting selfish because I'm not doing exactly what it is I want to do. 

How do I address the situation without giving her the idea I want to breakup, or simply how do I counter the doubtful thoughts?
