I don't think you're unreasonable, but there are ways to say it that can SOUND unreasonable. Your other problem, and this is just my opinion, is you're dealing with an inherent problem in wiring: If you have a woman who has a career and enjoys that career, she may not be wired to be a stay at home mom. Birthing does not necessarily trigger all these massive maternal hormones that make you want to coo, shop for bibs and sing along to Barney.
I've done both, I did the stay at home mom routine, and the working mom routine. I can honestly say that I was the absolute MOST depressed I've ever been in my life staying at home with the kid. Don't get me wrong, I LOVE my son, but not everyone is wired to be around children 24/7. I am not one of them and I am not unusual.
Being around children constantly, particularly from the age of 2 to school age, is absolute one of the most psychologically and emotionally demanding things I've ever done. And it has NOTHING to do with the lack of adult interaction, because I work from home now and have done so every day for the past 4+ years. Hell, I've gone weeks without seeing another human face to face with the exception of my husband when I've been snowed under work wise.
So, Clockwork, if you are dating degreed, professional women you are going to run into a shitload of resistance because you are dating women who probably know they are not wired to be stay at home moms even if they aren't aware of it.
It's really not so strange, throughout history women of many cultures have gone out and hunted and gone to war alongside their men. This idea of big strong man catches fish/fragile delicate woman cooks it, isn't necessarily what we've evolved from but nobody wants to believe that. The archeological evidence says otherwise.
