To come to India you ought to have a work Visa and for that you should  be employed in an Indian company or an international company having its subsidiary company in India.

As your wife is an Indian citizen she will have no problem in staying in India.

India doesn't have dual citizenship.

You can get a tourist Visa easily and as your wife is an Indian citizen that would also help as you may extend the same.

If you get a job while on a tourist Visa that is good. You may now get a work visa stamped and come back.

As your wife is an Indian citizen that would be a tremendous help to you as you may extend your stay.

I have a file from the ministry which lists the details regarding employment Visa process. 

I can share the same with you if you're interested.

If you are UK citizen you cannot work in india unless you have work visa

You cannot work on tourist visa 

Tourist Visa is granted to a foreigner who does not have a residence or occupation in India and whose sole objective of visiting India is recreation, sightseeing, casual visit to meet friends and relatives etc. No other activity is permissible on a Tourist Visa. The Tourist Visa is non-extendable and non-convertible.

Best option is to come to india on work visa 

If you are not planning to move to India, then nothing compels you to take a work at India.

If your wife do not want to return to UK you cannot force her to join back.

if you are a foreign citizen and want to get an employment in India, then you may have to look for one in India based on your current status. 

There is no specific visa called Spouse visa for India. For any foreigners married to Indians, you can get an Entry visa (X) through any of the FRROs in India.

This visa doesn’t give you any rights to be employed or do business, but you can stay for a long term in India on this visa.

If you are getting a spouse visa through an embassy of India in your country, the process is different.
