I have a lovely mixed group of friends who were /are a huge support to me after I became single unexpectedly several years ago now.
In lots of ways we're very different, literally from all walks of life, but we have a shared interest and organise outings, including trips abroad around that.
Some are married, some are single, some travel as couples, some partners don't join us.
One man, lovely, always good as gold in terms of respectful and appropriate behaviour, never brings his wife. She's not interested in the "thing", but I've always thought they seem to have a lovely relationship. They're often away for long weekends together, as well as both having busy lives with their own interests.
Anyway I was out with him (and others) last night. We had a good time, had some drinks. I don't remember anything inappropriate being said or done (and I wasn't that drunk!). He'd paid for the cab, I gave him a quick hug as I got out of the car, thanked him and said I'll pay next time we're all out for breakfast, which is a usual arrangement for us.
He messaged me to say he'd got in safely (also usual in our group) but also said maybe we need a chat when we're sober? It was late and I didn't really know what he meant, so I ignored it thinking I'd ask him face to face when I next see him. Then he sent another saying sorry, just the musings of an old fool. (He's late 50s, similar to me).
I've no idea now, but he obviously thinks something's awry...?
Atm I intend to ignore the whole thing....but we're going away for the BH weekend.
Fwiw, I am no longer single and very happy with new man, which this man knows, and has previously made a point of telling me how pleased he is for us. New man is coming next weekend and is friends with the "old fool"
