<human>: Can you condense the text into three sentences or less?

My boyfriend (24M) and I (22F) have been together about five years.  We have lived together for about 3 months (we share a room in a house with 3 other friends).  He is a great boyfriend.  I trust him completely, he is caring and respectful, we value the same things, etc.  I know his family very well (we are from the same town) and we expect to get married eventually.  So why do I have such doubts about our relationship?

I haven't felt close to him in a very long time.  I don't feel like I can talk to him about things that are important to me, like he doesn't "get" me.  He's the happy-go-lucky type and doesn't ever see anything wrong in our relationship.  I think that if I tried to suggest ways to strengthen our relationship he would think it was ridiculous. A few months ago I tried to tell him that I feel somewhat bored and he hasn't said anything about it since.  All in all, I am just underwhelmed.

How do I deal with these feelings?  Should I try to get him to go to some sort of counseling with me?  We are very young, so sometimes I think that going to counseling or trying to "reignite the spark" is just stupid, and I should break up with him and find a new life. 

What's more important?  Security (I know he's a great guy, would be a sweet husband) or a "connection"?  I know the honeymoon phase doesn't last forever, but should I even be worrying about the future while I'm so young?  I'm a senior in college and plan on going to grad school, probably far away.  He says he'll go wherever I go, so I feel I need to put on my big girl britches and commit or drop the whole thing soon.
<bot>: I could see myself marrying the guy or breaking up with him.  How do I deal with my ambivalence?
