I'm 33, so is DH. I had the perfect one-in-a-million kind of job. Interesting job scope, pays decently, 10 mins walk from our home (ridiculous coincidence as we're pretty rural), fantastic environment, my manager and colleagues are more friends than just coworkers.
2 years ago I found myself getting closer to this colleague. She's divorced, around our age too, no kids. It started with just group lunches with the rest of the office, then monthly wine sessions with some coworkers, then just us going on hour long walks on the days we end early, staying back late so we could talk, and a holiday with just us 2 for 16 days to Australia last year while DH went on holiday with his brothers.
I'm bi, she's mostly straight (in the sense that she says she's never thought about it when we were on this topic a long time ago) but there's been flirting in the past few months. Nothing explicit but things like "this meeting would be better if you were here" or "wish I were back in Australia with you" from her.
I like her. Too much. It got to a point where my mood at work depended on whether she talked to me or if she was laughing with other people. Some days I got so jealous it's ridiculous. One day I was home celebrating our anniversary with DH and all I could think about was her. And so, 2 months ago, I quit.
Applied for everything I was qualified for and the best I could get was a job with the only positive being that it pays 22% more. It's bloody 1h away, less varied job scope as it's an MNC instead of a SME, and the title is a bit 'lower' than my previous one because frankly my previous company was a bit old-school so only needed to do very basic IT tasks.
I regret it. So many trade offs when in hindsight I could've just cooled off a little and it'd maybe be fine.
