Hi Jpeg, the "trial divorce" was more of a more agreement than a legal one. I learned (this is pre-DB) W was on dating sites and dating other men, and so I gave her a Stipulated Divorce Agreement. She refused to sign it.
So I came up with the idea to let W sow her wild oats. I suggested to W that we release each other of our marital vows for 3 months, and she agreed.
This was not a good idea. Though I made clear to W on 7/1/2014 that we were still married, for a long while, she continued to see herself as "single". And only until the last several months has she slowed down her involvement with dating sites.
