I have a work friend of around 10 years. He’s married and I feel like our relationship has always been purely platonic. We were in the same team for about 7 years and during that time used to lunch together. Full disclosure I did have a slight crush on him for the first year or so but there was never any flirting, decent unspoken boundaries - we weren’t texting and he’s not on social media, no discussions on relationship issues or anything like that. I got over it.
Now I’m in a different team and I see him once in a blue moon and we IM. He’s recently told me his marriage has broken down. No drama, they’ve grown apart, separated amicably and are co-parenting. This was a few months ago. A couple of days ago he text and asked me out on a date.
Basically I’m concerned people will think this has been an ongoing affair and I’ve broken up his marriage. There will be gossip in work which won’t particularly affect me and I’m worried about what his STBX might make of it. If you saw it from the outside would you think “affair”?
