Ya, move to ORD and your wife will have a real job while you work for a regional. ASA/XJT/Skywest have ORD bases, Eagle as well as others. You can jump to the UK fairly easy from ORD as well to help your mother.

Sounds like your current carrier is stringing you along with the Avro possibility, and if they can hire street CAs before you get a shot then that blows!
