All right, here is a topic I think I can contribute alot with....
My girlfriend of 2 years and about 7 months and I just broke up about a month ago because of this very same problem. Man, we were just fighting about everything, very little things would upset her or me and we'd start.....we have been through many great things together so that has kept us together but at some point you have to stop it. I, during all this time have tried saying stuff but find it very difficult to say anything without upsetting her more. I try to find what Im doing wrong and avoid it but in reality when you're in that mood, anything will spark the fight. As I said, I tried saying stuff many times and had a very hard time doing so I tried to say it in different ways that didnt seem so hurtful. It really never worked so I ended up talking to her and telling her I think its better to call it quits for now. Who knows maybe later on, it can work, we might need a fresh start, maybe thats all we need but if we stay together right now, we're simply going to kill each other.
Life can be very short, can be cruel, amongst other things and we really must make everything that we can out of every single day. I felt very bad fighting about the dumbest things you can think of and it got very old. Even though I was very patient and tried to do alot of stuff do fix it, it just didnt work.
My best advice is, if you love her and want it to work, talk to her, be as honest as you can, regardless of how hurtful it may sound. IF she feels the same way as you do, it can work out. If it doesnt then hey, at least you tried, like I did. Dont give up just yet, work together on it as a couple and if at some point you feel like you're about to kill each other, it may be time to take some time off.
Let each other go, if you come back, you just might be meant for each other...
