They're still good friends. It just seems that there's alot more moments this Season where Fry get's mad at Bender for something. Fry definitely has more interest in Leela than Bender nowadays, but he's still his best friend and enjoy being with each other normally.
It's time for Fry to move in with Leela. Bender should live on his own. This will teach him how to treat his best friend respectfully. Or not. Fry will be OK anyway
That'd make a very good plot for Season 8, assuming that Fry and Leela are going to stay married at the end of Meanwhile. Though it would be pretty sad to see Bender living alone or Leela cramping up living with the 2 guys at the end of the episode.
