Yes, it gives you a glimpse of how confused she feels.
This is also the reason you need to emotionally detach from her drama, or it will pull you in. If she's in a good mood, you are fine. If she's in a bad mood, you are still fine. Your life is not based on her mood swings.
Sure it hurts to see her go through this, and not knowing what she may decide next. It is so important for you to remain strong and solid. Sometimes she will want to lean on you.......and sometimes she'll want to kick you out. So either way, you'll need strength.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
