What Should I Expect When Moving In With Someone After 4 Years Of Long Distance?

I’ve been together with my boyfriend for almost 6 years now, 4 of which were while I was away at college. We first started dating almost 7 years ago, and have known each other for almost 8 years. My question is this – I will finally be graduating and we’re planning to move in together before I start my new full time job. We’re going to be coming out of a long distance relationship straight into living in arrangements, so I realize this is not going to be easy and we must take precautions. What tips do you have about the situation? Is there anyone who has done something similar and has some advice to offer?
