Personally, (As the token man), I think that the OP is not necessarily being unreasonable. After all, we're all entitled to our list of requirements not just in partners, but in life in general.
However, she has no right to criticise him because he has a different outlook to like.
Ambitious people know what they are capable of and strive to take the next step up and challenge themselves to go out of their comfort zone. Self improvement, confidence and the willingness to learn and work hard is a very attractive quality.
Unfortunately, as much as these are indeed attractive qualities, none of them necessarily lead to higher wages. As for hard work, don't get me started. The binmen (bin persons?) round here work f**king hard, but I doubt that they are on six figure salaries and driving Jaguars. Indeed, the last time I did what I would describe as "real" work was a year ago, and I am paid around 35k for the privilege of sitting behind a desk .
Let's talk about that 35k a moment. I am an engineer, I design control systems for ships, and I bloody love what I do! Yes, there is well paid overtime on site work, but this is long hours on dirty, smelly, hot ship builds.
(And I am fully aware that many people are working in far worse conditions for much less money. That is the irony of the system in developed countries.)
There's not much further financially I can go really. The only way that I am going to "Improve" myself as described by some posters is to give up the job I love, and to move into management.
Instead of making things work and solving problems, I will be sat behind a desk and carrying out staff appraisals.
Or do I train as an accountant? Or in pharmacy sales to really "Better" myself. Even if as the OP leads us to believe this wouldn't involve extra hours I would detest my job instead of loving it! No offence to the people who do these, but personally I cannot think of much worse.
The money I do earn is enough to keep a roof over my head, food on my plate and beer in my glass. Could I support a partner on my money? Yes, if the brown stuff hit the fan, plenty of people do it on less than me. I'm not looking for a kept woman though.
Am I unambitious? I want to learn absolutely everything about my job. I want to be the best damned engineer that I can be. I want to design bigger and bigger systems, I want to teach people what I have learned, I want to help people solve their own problems, I want to be the go-to person for advice, I want to be known as a friendly, helpful colleague.
Does more money come into these wants? No it doesn't, I am doing this job to learn, develop and challenge myself, but above all to survive.
It would seem that I am not ambitious, and I certainly won't be having children with the OP anytime soon. And personally I am grateful for it.
