Having lived in Bahrain and met many Expat pilots over there, do not expect to return to the US or "home" very often. A commitment to work for GF means you are commiting to living in Bahrain. That being said, Bahrain is a GREAT place for singles of all kinds... not so much for couples. That is an OPINION, of course.
PM me if you have questions about Bahrain as I still know several of the "good" places for night life and expat life.
