Before you pack up and move to Daytona Beach or Prescott, let me throw my two cents in. At 18, a ten year commitment seems like forever, but when you're in your early 30s it'll seem like nothing. I knew plenty of guys who went into military aviation to with the intent of becoming airline pilots or avoiding having to carry a gun and sleep in the jungles of SE Asia, only to decide military aviation is where they wanted to stay.

I've flown with lots of civilian only pilots who wished they had flown in the military, but never the reverse. Serving your country will probably be the second most important thing in your life, right behind being a parent.

That's not to say military service is all wine and roses. Military flight school will probably be the most difficult thing you do in your life, and there's no guarantee you'll get a pilot slot in the first place.

The people you associate with in the military will be a cut above those in civilian life. having said that, the military will break your heart...repeatedly. You will watch the finest people you know get passed over for promotion or command, and you will see butt kissers and backstabbers step on others while climbing the ladder. You will be disappointed with aircraft assignments, duty assignments, and a myriad of other issues. You'll serve under great officers and buffoons. You'll come to realize the military is a bureaucracy first, and defender of the nation second. IOW, the ideals don't live up to the reality. However, when it's all over, you'll realize, by and large, you'll never work with people with as much integrity or sense of purpose again in your life. That's the final way the military breaks you heart.

From a practical standpoint, you probably won't get your first choice of aircraft. You're AF ROTC, so I won't talk about helos in the Navy (about 1/3) or Marines (about 2/3). If you go fixed wing, you can leave the service confident you'll eventually get an airline gig. The reserves are an excellent way to supplement you income the first few years after leaving AD, a great plan B during strike, furlough, or while job hunting, and guaranteed retirement benefits when you turn 60.

Long story short...just because you're not positive about the military doesn't mean it's not for you. I'd hate to go through life wondering "what if..." Most of the (relatively small) regrets in my life are because of things I didn't try, not because of things I did try.
