I'm in the same boat OP. I have a love/ hate relationship with the dating apps. I delete them, then hear Tinderella stories from everyone around me, including on MN, then I wonder if I'm doing it wrong, I go back on thinking it'll be different, only to delete it again. The cycle keeps going!
My marriage was very toxic and emotionally abusive but I'm looking for my right person and have decided to view singleness as prep time: like going back to school as a mature student; you learn with intention, and soak up as much experience as you can, and just like school, you tell yourself it's not forever and it will fly by without you realising, so relish in it and you will emerge an even better version of yourself.
What I am doing and have done is a lot of reading around relationships, attachment and emotions. I do not want to be attracting the wrong men, and any man that I do end up dating, I'd like to make sure I get it right so these books really helped.
I've joined some airbnb online experiences which I loved.
I'm exercising- not running or anything strenuous, but Yoga and Pilates is just as good at home
I'm journalling- any crap that comes into my head that makes me sad or angry goes down on paper, as it is cathartic.
I'm moving into my own place for the first time with my son so I am really getting into the zone of visualising how I'd like the place to look, doing plenty of window shopping online.
Weekly at home spa treatments- and taking the time to really enjoy what I am doing, so it can be a ritual.
I'm looking into joining an art class; pottery maybe as I can make a few gifts for friends this Christmas and for my home
I also plan little road trips with my son- granted these days it is somewhat difficult, but last year it was great fun and filled up our calendar.
When I get low, I get VERY low, and my plan is to fill my days with things that I like that make me happy- and inject a bit of spontaneity with my son. When you do little things that make you happy and do them often, it doesn't give much time to think of what else you perceive to be missing.
Fill your own cup so to speak- and mend any cracks :)
