I've met up with some wonderful people through the internet (some dating when I was single, and some just friends through forums - TAS and others.)
After marriage breakup, I found it a good way to 'get back on the horse', although it did mean that one very nice bloke had an 11 mile walk and no action because I realised I wasn't ready yet. (Sorry, Nick.
)
I even met up with someone who lived on a Pacific island! We'd struck up an online relationship through a forum and had such a lot of fun with naughty chats, I decided to detour on a trip to the States and meet up with him. I'd asked him what would we do if the chemistry didn't work in person; he said, "Bring your laptop and we'll carry on chatting online!"
Neither of us expected that to be the case, but in fact, it was - probably just as well!
Then I used one site to find someone to show me San Francisco when I was going to be there on my own, just for 24 hours. We dated for a year! And are still in touch as friends.
I did meet some men I didn't want to see again, of course, but only one that worried me a little - and he was the only one I'd had any misgivings about meeting up with, so I simply didn't meet up with anyone else if I had any misgivings. And a friend always had full details about who I was meeting and where, and would have taken action if he hadn't got the "Safe and sound" text after the date.
And then, when I'd decided that I was "finished with all that" and would be a happy spinster for my remaining years, I bought a farm with a female friend and met up with some people she used to work for, who had a nephew who farmed nearby to our new farm... and the rest, as they say, is history.
