Hard life after ILR

Hello people

it was only a year ago when I was taking advice from nice people here in forums on how to apply for ILR and I got it ... I was very happy and life was just smooth but now a very sad thing has happened... my partner is cheating on me and it looks like my marriege will be over soon... so here I am again to find out where do I stand...?

Here goes my brief immigration scenario: I came to UK 7 years ago on student visa. At the end of my studies I met my current wife and we got married finally in 2005. We applied for spouse visa in 2006 and in the beginning of 2008 I got my Indefinite Leave to Remain in UK. My wife now wants to divorce me just 5 months after I got my ILR. She said that she don't love me. My life is completely shattered...I dont know what to do becuase I only stayed in UK for her after I finished my education

I need to know how this divorce (if it happens) will it effect my ILR status and will it effect my Naturalisation application which I was about to file...? Will it also effect on the duration of me obtaining the British Passport. I am working here full time and have a small business too. I pay taxes and every thing else is just fine and has always been according to law. My current wife and me have no joint property however we do have some other joint finanacial committments which we have been meeting successfully so far.

I willl strongly appreciate any advice that I may get from you.. thank you very much in advance.
