ha.. I remember when I used to worry about splitting time with girlfriend and friends. Now it seems a lot easier to balance, maybe because most of my friends are also in relationships, so we either go out as couples, or us guys get together so infrequently it's never really an issue when it happens. I also play a lot of sport, so that helps with the whole guy time / time away from the other half. You've just got to do what you think is right, at 19 you've both still got a heap to learn.. Enjoy it, but don't get too caught up in the whole relationship thing, if it stops being fun then move along, there's loads of women out there, loads!
