I’m male, late 50s, have a job I enjoy mainly WFH and only call into the office once a month or so. 5 years ago I had a brief relationship (3 months) with a colleague who is still in the office. Ended amicably, we get on well professionally and have each settled down with someone else now. The relationship is long forgotten about and has never been an issue. I met my GF two years ago and we’ve been living together for 12 months. We were talking about relationships at work a few days ago as part of a wider conversation and I told her about my experience. My GF is now insisting I quit my job so I don’t come into contact with my ex. It doesn’t seem to matter that I barely see her, it’s never been an issue and she’s in a long term relationship of her own. I’ve no intention of quitting a job I like with no guarantee of getting a new one paying the same amount of money, especially at my age. AIBU to stand my ground on this? My GF is absolutely insistent I leave, and it’s making me doubt that she’s the one for me even though I think the world of her.
