The season finale

The season finale of "Dance Moms" left you hanging.  Abby starts to cry because her "star" didn't win, and she failed to complete her solo on stage.  All of her other students forgot their solos every once before and they have never seen tears come from Abby's eyes.  She didn't even go to awards.  That is very disrespectful, as being a studio owner and being a dance teacher.  They left us thinking she's leaving?  Saying I need a vacation away from this? Not professional what so ever.
