Can you move to the middle and you both commute? 9o mins is not that far away. I have friends that commute over an hour everyday just to get to work. If you're serious about committment and moving the relationship beyond the honeymoon period then the 90 mins wouldn't even be an issue for either of you.
10 Months of weekends is hardly any time invested in each other at all. Perhaps in time you'll discover that you don't like her enough to move or you like her so much moving will not be an issue.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
