There's been drama again

On Monday evening, R told S that I will be living with R next year and that the three of us roommates won't be living together again. Apparently, S didn't like the idea of that at all. S throws a fit. She claims that R is abandoning S and not caring anymore now that there's a new girl in her life. Then S proceeded to punch R in the stomach. (R later claims that it didn't hurt that much, besides the fact that R was hungry at the time). S climbs out of the car, sobbing like crazy and slams the door. Very hard. That night S went to go spend the night at a friends place.

So this past Wednesday was R's birthday. And that morning, S hugs R and tells her, "I'm just scared of having to live on her own."

And now, it's Thursday evening, and everything is okay. S's room door is open, and she's friendly again.

*cough* I can't help but feeling a little suspicious that something is going wrong. How did S get over her distress over 2 nights? S usually takes longer than that, she takes months, in fact. What's going on? I'm a little worried, my eyes are throwing weird glances. I'm confused. My instincts tell me that not everything is what it seems.

I meant to ask R about it, but both of us are currently swamped under huge amounts of coursework we are busily trying to keep up with. I want to discuss some things with her. Both of us have been communicating more about our relationship these days. Reminisce about the past, and contemplate the future.
