It's not and I'm actually happy for Debbie.
However the selfish side of me doesn't pay monthly for empty room's or beds.
Even worse is the chance that when George leaves and Debbie comes back she becomes just like Valeria or Megan.
As for whether Deb and George had sex in the apartment, I would have been fine with it.
Hell, if Debbie had her own room (I hate the fact they have two girls in one room 😠) it might have happened.
