Open Question: Need some realtionship advice ?

Hi everyone thanks for helping before hand! I have been dating my Girlfriend for 8 months. I cant Speak for her but I can at least say I like her as a person more than any girl i've ever experienced or have been attracted to. I've had these feeling since the first night we meet and they keep getting stronger. We are both very attractive people, have never had a fight - not one, both atheist - which is hard to find and is important in the way we live our life and carry out our ethics. We hang out all the time, gone on trips, just got back from xmas with my family, into art, politics, working out ect, ect. Prior to us meeting we were hell bent on staying single and "free" forever. The issue is not our relationship - i think that its excellent but this is for the both of us our first relationship. Out side of prior dates and us both sleeping around a bit at one point, this is all we have to go off of but it just seems to good. Is this what every relationship is like when you find someone that's compatible? At times i feel like im taking our relationship too serious and feel like im missing out of other potential great relationships with women...... but I also know i'm not really compatible - relationship wise (i have tried), with many women for anything more than a one night stand (i'm attractive and in great shape but to into classical music,wine,art. law and political policy - which bores women ) and to feel anyway close to the way i feel about her is a tall order since i have felt this way about her from day one, and find her eternally attractive. Because of our sick sense humor, world view and passionate interest in art and politics/law - which may sound interesting but, when it comes down to it most people are just saying that stuff to sound interesting and after a date i could tell.. Most women and men really are not that deep or passionate about anything and, many people look down on you for not being religious also. Another issue is that i'm going to law school and while she potentially may come with me at the same time she's thinking of moving to europe.While I would love to do that I need to finish law school. Basically from experience would you stay together no matter what as long as its going great? Or are we just enthralled that this is our first real relationships? does a relationship like this happen more once you get in the groove of having a realtionship/s ? For the more experienced people, in hindsight did you make the right decision when having to move to a new job,school ect ect, or wish you should have stayed with your first love cause you never ended up finding better. I guess my worst fear is ending a relationship on such good terms because of conflicting futures; issues which upon graduation we will have to deal with.
