I'm not dating either and have zero plans to do so any time soon. While I do spend a fair amount of time with friends and family, there are weekends when STBX has the kids, and I don't have any definitive plans. Here are some things I have done (and also some things I'd like to return to) to give you some ideas:
--I've returned to baking things I like. All I ever made were certain things that STBX liked because he hated when I diverged from his preferences. I'm going blueberry picking in a few weeks and making a pie! I also got a great cookbook called Vintage Cakes that I plan on making some neat cake recipes from.
--I have taken yoga and meditation classes and really enjoyed them both. They're great for teaching mindfulness and living in the moment. I highly recommend one if you have a class being given near you (and many churches, local fitness centers, and even community ed classes offered by your local school district have these if you don't have a yoga studio in town).
--Any hobbies you gave up that you'd like to return to? I'd like to rejoin a singing group, play this summer with a community band, take a knitting class as a refresher, meet up with my local NaNoWriMo group (writers' group), have another book club meeting... these might not be your thing, but the possibilities of what you could do are endless.
--Check out your local library for classes, presentations, movie nights, and other community events. They are also a great way to feed a book habit cheaply and to see all of those movies you've been meaning to see for free!
--Go to a movie alone. Seriously. I finally summoned up the courage to go last summer and wished I hadn't waited so long. It was really fun, and I loved not having to explain the movie to anyone!
--Support groups: my Divorce Care class was about support, but I also made friends with the core group, and we had a couple of potluck parties together. I want to get back to seeing them again. That's a great way to build a support network and feel like someone has your back. The leader calls me from time to time to check in and see how I'm doing.
--Meet-up groups: Some have had success on here with those; I personally haven't seen any local groups that I like, but that might be something for you to look into.
--Learn something new: I'm much more adept at fixing things and landscaping because I have to be, but it's certainly been great to learn new skills and to not have to ask for help. You could also think about taking a class in something, whether it's pottery, philosophy, salsa dancing, or woodworking. There are often lots of classes that you can take on the cheap.
That's all I can think of for now. I know it's hard, but you'll probably come to realize how valuable this time will become for you. I wish that I had realized how great it could be to be single when I was younger. I made a huge mistake by clinging onto my romanticized view of STBX because I was so desperate to be part of a couple and was in love with love. Now, I am deeply appreciative of the quiet, restorative nights that I have for doing whatever I want and for the days spent that I've shaped myself. I feel more productive, more upbeat, and more alive than I have for years.
