@Btru78,
I dated a guy about three hours away for quite a while. I happened to love him and he loved me. Also, he would make the drive in the opposite direction approximately half the time. Can you ever meet half way?
You say he's great. Do you like him as a person? Does he seem to like you?
What about your depression? If it is clinical depression, you need to be seeing a therapist, although you didn't say if you are or not. I've plenty of friends who have been and are treated for depression who are happily with a mate. Well, as happily as anyone else.
