I love my girlfriend very much. We just celebrated our six month anniversary and things are going very well...except for this new attitude she is 'developing'. Every so often, (and more and more lately) she has been extremely snappy towards me for no reason. She literally does it for no reason, and I have no idea why. I don't just take it like a puppy being scolded; in fact, on one occasion, after telling her to stop and that she was being ridiculous, and her continuing to do so, I left her apartment in the afternoon when we were planning to spend the day together. This incident was pretty big. When I left, I texted her saying, 'Don't you dare call me later, saying how sorry you are, because you continue to do this, and I'm not just gonna shrug it off every time.' Sure enough, just as I got home, I receive a call from her, crying her eyes out, saying how sorry she is, and she realized how ridiculous she was being and that she will never do it again. Since this time it was more serious than past minor incidents, I genuinely talked to her for awhile, and eventually accepted her apology, and told her that everything was alright. Well, just today, a similar incident happened. It wasn't as serious as the 'walking out' incident; that was the climax. But the fact that it's even still happening, big or small, just makes me feel like she is lying when she calls me crying, saying that she is working on it. The crazy thing is, when she called me after this afternoon, after this morning when it happened, she told me that I'm the only person she treats this way. There is no doubt in my mind that she loves me very much. She has shown it in so many ways that she loves me more than anything, and that she wants us to be together forever, that type of thing. But the thing I'm trying to figure out is if she loves me this much, why I am the only person she treats this way? Does she just assume that she can treat me this way sometimes because she knows were so in love that it will eventually get resolved? She knows exactly when she's doing it, yet she does it anyways. Today I told her I'm not putting up with this anymore, and that we should take a break, so we can figure out some things. So as of now, we are on a 'break,' but I know for a fact that later tonight she will call me crying saying how sorry she is. But I've heard that story before. What do I do? I love this girl, and I want to marry her someday, but this is getting really annoying.
