<human>: Let me just start off by saying that I do absolutely love this woman. To the point where I'd do anything for her, and I know she would do the same for me.

I let myself start arguments. Especially over petty stuff, that shouldn't even matter. I don't know why I over-react, I don't know why I let little things bother me. I don't ever want to fight or argue with her, but I find myself saying some pretty spiteful things lately. And I know if I can't figure this out soon and put a stop to it, I'm going to end up losing her. It's lead to too many arguments lately. I don't know what's wrong with me.

It could literally be something as small as she doesn't want to spend the night with me. It doesn't make me go into like a rage, but it kinda disappoints me. I don't know how to make that stop either.

Can you condense the text into a few key points?
<bot>: I let little things bother me, and it's causing fights with my girlfriend. I don't know how to make myself stop.
