My girlfriend has has an attitude since yesterday night. And every time she does, instead of answering the question like an adult, her reslonse is, "I'm fine" or something similar. She says anything to make it seem like her very obvious change in behavior isn't actually a reality, so I no longer ask, but its becoming more frequent now, and more annoying. What would you do in this situation? I haven't missed any anniversaries or birthday in case your wondering.
