I went to a low cost one in Fairfax. I had a good experience. My outcome was not good as I did not want out of the marriage but my husband did.
He served me, did not communicate for a long time and then we spent years in court.
Don’t do what I did! But the mediate was overall helpful. I think I was just a “little out of it “ because loved him and our kids. I was also very grouchy in middle age, and said and did a lot that I regret over two years.
Huh! FWIW !
