To me, you kinda have to deprogram you brain from what your schedule was and start a new one.
For about 4 years prior to my initial seperation I was tending to my kids about 75% of the time, when it was suddenly cut in half there was a huge void there.
Im a guitar player and fortunately the guys I had played with for years, decided they wanted to start playing again and approached me, I hadnt played seriously in a few years, so a good amount of time was spent just getting my chops back up to speed.
I also learned I liked to cook, I had cooked for my kids out of necessity, but once the divorce started I cooked these big meals and froze or saved most of them for lunchs ar for late, this turned into a huge cost saving deal for me
I hung out in some bars and learned how to really play pool, had never really done it before, but just to have live company, and be doing something thats what I did.
Anyway, you have to reschedule your life, with and without the kids, sounds simple but its not that simple
I would encourage anyone this close to their divorce from wasting a lot of time on dating sites, just my 2 cents, but I guess thats normal these days, Im more old school and want to kinda watch someone from a distance to see what they are really about before I would get close
