You sound like you are doing well. Your W sounds like so many of the WAW/WW spouses out there. She is not happy with any aspect of her life. She doesn’t like work, family is evidently not cheerleading her D decision. I went through some of the same. It was also at Christmas time and then even more so just after the holidays that my WAW starting rethinking things. She said she wanted to try to put things back together shortly after the holidays but that was short lived with her actually trying for a month to 6 weeks before just going through the motions for several more months and then finally filing.
Very interesting how you would likely not even date the woman your W has become. You seem like you’re on the right path. Keep doing things for you. Your W will for certain notice it. She may or may not be impacted by it. Or she may be largely impacted by it but you won’t want her as she is. That has happened more than you might suspect. Just keep living your life. Keep doing what you think is best. Let her come to you - or not.
As for OLD, don’t, just don’t. Trust me, looks can be very deceiving. You may see on paper and in photos women you say, wow, I want to meet her, until you actually do, and then they act much like your W did at Christmas - or worse. There are a lot of misfits in The Land of Misfit Toys that is online dating.
