Any tips on how to survive college while in a relationship? if u did it, how did u make it work?

my bf and i have know one another since middle school, but we became more than friends after graduation. we graduated in 05 and then in jan of 06 we got together and have been ever since. we've done the whole college thing while in a relationship for 2 years now, but instead of it getting easier its seems to be getting harder. trying to make our individual dreams come true, looking for jobs...etc, it can get difficult because as much as u want to worry about only yourself, you end up worrying about how it affects the other person too. if i just saw him as a bf who i felt it would nto work out with then i wouldnt care as much, but we have a good realtionship and i could see myself marrying him when i am ready. shoudl we eventually take a break and do what we need to do, or can we make it through? have u ever done this, and then later get married and it work? or how about those of u who are doing it right now, hows it going for you??
