I am not divorced. Although WH was the one who left and eventually initiated divorce paperwork, he flip-flopped constantly through the process. It took him over a year to start the paperwork (during which time he talked repeatedly about coming home and how we were going to make it through this and he just needed time). Then out of the blue, he couldn't get divorced fast enough. Two months later, he was second guessing himself and told his attorney not to turn our final paperwork into the judge. Two months after that, he told me he missed our family and wanted to come home. He promised to dismiss the divorce case but didn't and just left things stagnating in the court. Things kept dragging out with him being neither here nor there, and it seemed like he was incapable of making a decision. Eventually, I had enough, packed my bags and left. When he saw I had no intention of returning, suddenly he was desperate to have me back, started seeing a counselor, and dismissed our case. We are currently still married but living separately.
As for dating, I waited until we had signed the papers. In our situation, we had already been living separately for almost a year and a half by that point, and although I have no concrete proof, all signs pointed to him living with the woman he left me for. I wanted, and felt emotionally ready to move forward, and I felt like he had already disrespected our marriage so much from his previous affair, plus current situation, it really didn't matter either way.
