Is AUTHOR wrong in the post ? POST : AITAH for pointing out that my partner could be earning a serious larger amount of money than I do by either committing to work full-time at he job or by committing to take on more people in her private business which is a similar thing to her day job but aimed at a different audience?

backdrop to this is that we have a reception schooler who she wants to be around for, her father recently passed away, both our parents live a significant distance away (hers more than mine).

the flipside is that by working standard office hours with no requirement for overtime she could earn around £9,000 more than I straight off the bat, she is significantly more qualified, we have a house which needs a fair amount of work (urgently in some aspects), she puts limits on when she will work privately (effectively capping her potential income), if I shifted position (without having undertaken costly further education) the likelihood of me being able to earn anything more than I currently do is slim to none without risking it all and becoming a contractor with no guarantied income  or that I would find employment nearby.

Is it fair that she gets angry at the near raising of the topic?  Is it fair that I get accused of being the asshole...an unreasonable bully even?

I get it...she's under stress and has no desire to progress into a managerial position and I get that her job is stressful.

Does the fact that I'm working a job I don't exactly enjoy, with no real prospect of progression, and no real chance of anything more than a side step into the unknown (better the devil you know kinda thing) have any bearing?
