If your relationship isn't going so hot (and you're not married with kids), then It might be a good idea to split up for a while. Breathe a little without her, easier.
Keep in mind my photo. I'm only 20. But it could benefit you two to see other people for a little bit. Try not to get jealous, but (as long as you don't do something too stupid out of that rage), I'm sure that will bring you back together.
I've got high-hopes for you, Kyle 895. As the old cliché goes, "There are plenty of fish in the sea," so see what's out there. It may help you appreciate or depreciate what you had, relative to this new potential.
Good luck :)
