I think you are taking this all too personally. She held off on filing the divorce decree until she got you to take care of the kids, the house and the dog while she had her fun weekend. Now she is critical of the way you did it? She could have paid someone to do it. But she didn't. She used you. Now she thinks you didn't do it well enough. That's her problem. Next time, if she really doesn't like the way you do things, she can pay someone.
OK, now she is back from the weekend. Things went well with OM, and she wants to proceed with the divorce. So? What does that have to do with you? Nothing. She would have done this anyway. She only waited to get the weekend away with a free housesitter.
Everything is not your fault. If the kids and the dogs are alive, you did your job.
