Relationship Slow Down

Is it normal for a relationship to slow down the longer you’ve been with someone? I’ve been with my boyfriend for almost 2 years, we used to be on top of it; telling each other good morning and goodnight every day, telling each other what we are doing, where we are going, just basically giving each other a run down of our day as it goes on. Now it seems like we only do that when we remember or i guess just don’t see it to be as important, i’m trying to get us back into saying good morning and goodnight at the least. I do understand that these are our college years and we want to figure out who we are and what we wanna do, so we’ve been taking some space from each other. I know it’s all gonna look out in the end but is this normal and okay? Any advice on how to be stronger or how not to lose the “communication”?
