non eea 5yr seeking help

[eeahelp]

Unfortunatley i have to resort to seeking information via this immigration board which i am sure has helped countless people in their search for help.I hope that this will prove fruitfull.
Due to my current circumstances in my marriage,which looks to be on the verge of a breakdown i have been forced to look into my options with regards to my immigration status,something which i have not been bothered about since receiving my 5yr family permit.One has to look after themself when these situations in life arise.
I married my wife who at the time was an EEA citizen(Polish),we married abroad and got the EEA family permit to enter the UK to start our life in Aug 2008.Once in the UK we applied for the 5yr Family Permit.This took 1yr for the Uk Border Agency to process because of their ''back log''.So start date of permit was Dec 2009-Dec 2014.My wife manged to aquire her british citizenship in Nov 2011.We have been married for 4yrs and have spent our time in the UK.I was in the country for 2yrs prior on the 2yr working holiday visa,if thats of any consolation.
So now i need to find out what my options are....never thought that it would come to this.Any help would be greatly appreciated
Further info required as requested in another forum:My wife was excercising her treaty rights and had applied for the workers registration scheme from her start in the uk.She has been in the same position of employment for 7yrs.All that info was requested in order for her to obtain BC.
