Can I stop my wife from filing for divorce?

I’ve been married 8 years and my wife is now saying she wants a divorce. She says she filed for one but I have not received any paperwork, and we are still living together. We live in San Antonio and I went to the courthouse in Bexar County and they said they have no record of her filing. I don’t want a divorce, I want to go to marriage counseling. Is there anything I can do to require my wife to attend counseling with me, or some type of mediation? How do I find out if she did file for a divorce?
