Whatever I like.
I've been away the last 3 weekends & I'll be away next weekend. (And I have a full-on job Mon-Fri). This weekend I've done a bit of cleaning & sorting, catching up on telly, I went out for lunch today, went out for a couple of glasses of wine last night, caught up on some reading, popped to the library, started packing for my trip away for a long weekend, had a couple of calls with people I needed to catch up with, did a bit of life admin, gym & running and a bit of yoga.
I know that some people think single women ought to hide and cry. I think being single is an entirely natural state of being, and I deliberately make sure I do the things I want to. Sometimes with friends, sometimes on my own.
Things I sometimes do - cinema (in the rare event that there's anything worth seeing), local walks or walking tours, day trips to National Trust or similar, museum (it's small and I know it well but I still enjoy it!), local talks & things (you need to keep a beady eye on local social media - but Heritage Open Days in September will have a lot of interesting stuff).
