FLR(M) extension complicated by spouse's work abroad

[Knotwise]

Hi,

I'm currently on a Spouse visa that will expire Oct 2016 and am living in Tokyo with my husband who is British and is working here as an expat. His project will be coming to a close at the end of this year and he has been given notice that the company would like for him to continue on the project but in a middle east location with a very good financial package.

I'm a qualified healthcare professional but unable to work in the Middle East. I would like to return to the UK to get back to work. We own a property but intend to keep renting it out and instead look for a flat in London to live in. My husband will be able to return to the UK every 6 weeks for 1 week if he transfers to the Middle East after this Tokyo stint at the end of this year. Would this arrangement meet the 'living together' requirements for an FLR(M) extension if we both rented a place with both our names on it and he came back every 6 weeks? Also, He will do no more than 2 years in the middle east and can quit as early as 6 months after transferring there.

If that does not work, should I apply for a Tier 2 visa at the end of my current spouse visa and then reapply for another spouse visa once my husband is back in the UK?

I would be grateful for any advice! Thank you.
