I don't know how I feel about the big city comment. I grew up in one and there was no limit of availability of marriagable men when I was in my 20's(I married in my 20's too and didn't let that fact pass me by), but I still know professional friends of mine(in thier 30's) who were not ready for committment to good men they knew in thier 20's(who are now married with children) and they have the same complaints you have, disregarding the fact that when they were younger they knew plenty of good men, but weren't ready to marry. I think a great book regarding this issue is "What our mothers never told us". I'm not saying your complaints aren't valid, but I'm suggesting that many single professional women have waited too long to start looking for a good mate.
ps I should mention that I met my husband through work in another city so even I had to look outside of my area. I'm just kicking around some ideas and I did want to say that looking back I am very happy I chose not to wait any longer to marry and looked honestly and with an open heart at my husband and what married life would bring and made the plunge at 26 instead of looking now in my early 30's and feeling the desperation of wanting children and not having a mate. I feel that pressure of my childbearing years being probably half over and I have 2 children already...I think the pressure would be unbearable and I had none and no hopes for a spouse.
Well I am. How incredibly self-infatuated! Personally, I find no reason to disagree with my wife on this issue. She claims the problem with professional women finding mates is they won't get off their fat a$$s and look somewhere different than the places their lives normally take them...even when those places are obviously non-productive. (It's not all about you ladies) They much prefer to complain about their circumstances than change them.
