[quote=itsj0nathan]When we bought the houses we were and we have kept everything seperate so technically i guess you could say she is living seperately. Im just trying to figure out if we can file married filing seperately and not have to pay the 8k back…[/quote]

The credit for married filing separately is reduced to $4,000 on each return.

Also, in order to keep the credit, the homes must remain primary residences for 36 months.
