how to protect my asset.

I married my wife 2 years ago back in china.(we don't know each other well), we started fighting right after she came here. Right now she is having affair with a guy and want to divorce with me. I have been working very hard to support the family(she is a house wife,doesn't work). we have a house in our name. Its reasonable to give some of the asset to her. But I think equally divide the house is not fair(I am the only borrower for mortage).
Is their any way that I can protect my asset?
thanks!
