lynn, I'm so glad you are able to take him t be seen by someone, even a reg vet is better than none. I hope everything works out and it's nothing TOO serious. Positive vibes and prayers coming your way ((((()))))
As for your female being lonely and depressed without him

I think all you can do is spend all the time you can with her and like peepers suggested-play her fav music and don't leave her in complete silence. Does she have a mirror in her cage? Might help a little bit?
Thanks for the update, and yeah, please let us know what the vet says. GOOD LUCK!!!!
