read my lips:
before making any actual decisions
you will be a completely different person then than you are now and whatever you find you have in common with this girl now that attracts you may simply not be there at a later place and time. you will change more rapidly through your twenties than at any time in your adulthood, in ideology, interests, goals, education, etc.
This post is the absolute truth, and I wish I had heard it 15-20 years ago (and that I had the capability of appreciating it at that time).
