Hello Indigo Warrior of Light...
You are 18... she's 16... it's time for you guys to explore... to fall in love... and fall out of it again... and, before both of you are mature enough to take a life long commitment... that process will have been repeated over and over again... and more likely than not... with different partners...
So, for the time being... just go with the flow... see what comes... and see what goes... and, don't worry to much about the future... enjoy the ride while it lasts... and, once it's over... chuck it up to experience... no big deal... most people who are older than you have gone through similar experiences...
The very best of luck to you... smell the flowers and listen to the grass grow... life goes on... and it's a wonderful adventure... enjoy it...
