I am sorry you find yourself here. My H walked out on me and wanted a divorce. I did the same thing you did. I talked to a lawyer and started the process. But after I left the lawyers office, I said to myself, I do not want a divorce and this is what he wants me to do. He wanted me to file because he did not have the balls to do it himself.
I gave him his space and only talked to him if it was concerning our D.
7 months later, we are working on reconciling our marriage. So far, so good.
