DH is seriously ill. I run. During this awful time with DH, running is a about all that's keeping me going, especially as the usual things like having a coffee with a friend aren't possible.
Thay say it's times like this when you find out who your friends are and this seems to be true. The people I've thought of as best friends seem to have disappeared. Very occasional texts, that's all.
However some running "acquaintances" have been brilliant. One woman is in touch almost daily and regularly taking me out for a run. Another injured runner invites me out to walk her dog with her.
Another man, I've known for a long time, but a much faster runner than me, so I don't usually run with him, has been contacting me for a regular weekly run. He treats it as a recovery run and I get pushed hard 
He's a good chap, I've been on a few social things with him in a group. He's friendly with everyone and real do anything for anyone type, but also a bit of a ladies man, although he's never made any kind of move on me.
He's also living alone, with a girlfriend he's not seeing much because of lockdown. I've met her, like her, but I don't really "know" her.
He's just suggested a second run this week.
So, a bit lonely and bored, looking for company and doing a nice thing for me? Or be very wary? I really don't need any added complications atm, but the company is doing me a lot of good.
