Getting bored?

if ur bored like mitch try it with a man

use toys and have kinky sex!!!

I agree, find ways to spice it up.. But if you guys haven't gone far yet (sexually i mean) DONT try anything sexual, because that could just make things worse. It might turn the relationship purely physical which would probably be worse than what it is now, and much stickier and more painful to get out of in the end. On the other hand, if you guys have gone far sexually, then I agree with Metric, toys and such are a good way to spice things up :P Or sexual activities in thrilling places (aka semipublic places). Just don't push her into doing anything she's not comfortable with!

Although.. On re-reading your post just now, I feel like being 'bored' might not be your only issue. If you guys are arguing a lot, and she's apologizing a lot, you probably have worse problems on your hands. I think you two need to talk it out, and find out what's wrong. If you're arguing over important things, you should talk it out and come to compromises over issues. If you're arguing over petty little things, it could just be you guys aren't happy together and it might be time to try taking a break from each other (maybe just a week or so where you won't see each other outside of school etc., so that you can get some time to yourselves and clear your heads) or if it doesn't work, you two might need to break up permanently, even though I know you two don't want to do that. Even though love is great sometimes, and I know you two probably feel like you want to stay together no matter what, you have to take a step back and look at your relationship. If you guys are unhappy more of the time than when you're happy, is it worth the pain? If she's continually apologizing, she clearly is feeling guilty and upset over this. So yeah.. what's most important is that you go and talk to her about what you're feeling. Bottling it up, or telling strangers online is no relief or resolution compared to talking it out with her.

Good luck.. I hope you two work it out!
