Can I still file for divorce, please I need help

my STBX filed for Child support in Jan of this year, and told the child support officer we were separated in Jan of 2010, but in actuality we were separated Aug last year, she gave that date so I don’t have to pay for any other months from last year due to our agreement.
my question is, can I still file for divorce in Aug this year after the one year and one day is passed from our separation, or the date she gave for the child support will be used against me in the court.
I really need an answer this way I can start the coaching service you provide via the site.

Thanks again, and I really appreciate your help.

The divorce can proceed in August. That is the date you actually separated.
