Oh, boy. You've got some problems that need immediate attention.
The good news is it sounds like you've got a pretty sweet guy who is very honest with you.
The bad news is, you're strangling him.
You're expecting, nay, demanding too much from a college relationship. I think it is admirable that he's putting his career first at this point in his life. That's how it's supposed to be, and you should be doing the same. Why aren't you? That's the real issue, here.
Breaking up with him isn't going to solve any of this. It will just happen again with the next guy, or what's worse, you may actually find someone who thinks the sun shines out your ass and you'll find out why that's not everything it's cracked up to be either (pun totally intended).
You need to focus on you. You should be able to walk side-by-side with the man you love into your future together, and it sounds more like you don't want to go anywhere, just stand in the middle of the road with him staring at you.
