Recently separated, still lots to sort out, not exactly "free". Says he wants to enjoy some time being single, which I've endorsed and said he should.
He's a couple of years younger than me (50s) and an interesting and attractive man. TBH if/when he wants to date, he's not going to have any difficultly.
Meantime he's texting me, his friend, up to 30 times a day, 4/5 days a week. It is all just friendly, sometimes there are bits about what a good team we make - we do some voluntary work together and if I'm away he'll say he's missing his partner in crime etc, but there's nothing sexual or overtly flirty.
I like him and enjoy having him as a friend. If that's all he is, that's fine, but I don't have any other friends in contact like this!
