Robert Pattinson has given cheating girlfriend Kristen Stewart an ultimatum on their relationship.
Robert, 26, agreed to take Kristen back after photos emerged of her affair with Rupert Sanders. However RPatz made it clear that this was only on a 'trial basis'.
Stewart, 22, cheated on Pattinson during her time filming Snow White and the Huntsman with 41-year-old married director Sanders.
Rob's said that he will make a long-term decision on their future as a couple by Valentine's Day 2013.
A source speaking to Now said: "Rob's planning to skip most of the upcoming awards parties and spend January focusing on his relationship."
It was recently revealed that Kristen will be starring in a sequel to Snow White and the Huntsman but it's unlikely that Sanders will be involved.
Probably for the best...
