Marriage visa

Hi everyone
I married German citizen three years before and  I got three years visa ,next month my visa expires but unlikely my wife and me have some family problems she said can't sign and give here documents to extend my visa? What can I do ? Any other option to get visa? She going to divorce me ! Please help me

If your visa is based on having a German spouse, it will become invalid the moment you stop living with that spouse.
You should contact your local Auslaenderamt to inquire what other options you have to get a visa. If you are working and earning your own upkeep, you'll probably have a chance.

Thanks
