Exactly. However, I don't think DH thinks I would cop off with S, but I do think he finds our relationship a bit weird.
To explain, me and S split a few years later than really we should have done. We got on famously blah blah blah but NEVER had sex or did anything other than things with all our mates. We were also each others' mates. Best mates.
However, when we did split, S went into a bit of a decline but I don't think that was really due to me, just the fact that he was on his own and also, to paraphrase, everyone ended up chucking him in the end. He drank far too much and took too many drugs and so on and then ended up in a weird almost sex free relationship with someone 22 years younger. The weekend I met DH he was there, it was a 'party that wasn't a party, it was just drinks' which lasted two days.
The Monday after this 'party' I met S in the pub where DH was picking me up (in his Porsche as it happened, but I didn't know this at the time) and S made some silly comment about how he could now see why I was meeting DH (although, obviously, he wasn't DH at the time!) However, DH is still going on about this as if it was the epitome of rudeness.
I love S a lot. I don't fancy him at all but I love him, his friendship, and he is a MASSIVE part of my life. And always will be - my mum has said the same.
Not sure why I gave you an edited autobiography but thought I will. Think it's helping me.
There is loads more I ought to add to paint a full pic but will leave it as not sure if it's either needed or appropriate.
