We did not live together all of 06 or 07 due to separation.can I still file jointly now that we are speaking and agree to file jointly.please help this is costly mistake .

You CAN file Married Filing Separately, but you can also file a SINGLE if you have been separated for at least the last six months of 2007.

You also have the option of filing jointly, because you ARE married.
