I'm constantly using fdisk on GPT and everything has been fine.

How did you end up in this situation? Did you copy the data from a smaller
disk to this 60G disk?

Looks like you could move p3 to the end of the disk and then enlarge p2
and then grow the XFS on it.
I'm not sure it's a good idea to use fdisk on a GPT disk. At least in the
past this wasn't supported and I don't know how much has changed here. I
didn't touch a lot of GPT systems yet, and where I did I felt frightened
by the whole EFI stuff :)
