If he was "The One" for me, I would know it, wouldn't I?

I've been with my boyfriend for 2 years now. He's a decent guy, we get along well most of the time, and we make each other laugh. I love him but I'm not so sure I'm IN love with him.

I broke up with him when it seemed like he would be moving to another city and living with a girl roommate for college. He thought it was a dumb reason to break up. Things changed and we're back together, and he's not living with another girl.

I'm just really uncertain. We don't fight too often - mainly because I am too reserved to start an argument when he does something that bothers me. But he is edgy at times and often speaks to me like a child, with a condescending tone that I can't stand.

I've confronted him about the issues I have - he often doesn't even realize he has upset me, so I know it's not intentional. He will always apologize sincerely when I mention it. But it's so frustrating that I have repeatedly asked him to make the effort to change, and while he says he will, I have not noticed any improvements.

I guess I struggle to find enough bad qualities to justify dumping him, but it just doesn't feel right most of the time. :/

I'm going to be a first-year college student in September, so I'm sure I'm going to meet lots of wonderful guys. My tentative plan as of now is to wait it out until school starts, and if I start meeting people that appeal to me more, I will (try to) gently let him down and tell him I feel I need to explore my options and enjoy college life for a while.

I'm just nervous because I was so incredibly guilt-ridden the first time I broke up with him. He was a complete wreck. And the night we made up he was more than convincing - the things he said and did were exactly how I want my boyfriend to act. So I know he's capable of being that guy. I have no doubts that he loves me, but he doesn't show it like other guys I've gone out with. I don't get it.

I have a pretty good idea of what the answers to this will be, but I would love opinions on the situation.

Will provide more details if requested. Sorry it was long.

Thanks everyone!
