Should I break up with him?

I'm somewhat in this position myself, and very confused, too. It will be a hard decision no matter what, but it definitely sounds like you need to figure some things out with yourself and figure out what you truly want. It's not fair to your boyfriend to stay with him and drag him along if you aren't feeling that loving "spark" anymore, but if you are truly unhappy right now then maybe it would help you to just ask him to take a break, not so that you can date other guys but so that you can think things over and make a decision that will benefit both of you in the end. Good luck, this kind of thing is always hard..
