First, Happy Birthday.
Second, I hear this a lot from men of a variety of ages. What attitude in women troubles you? Where are you meeting women? I honestly find that there is no shortage at all of good, quality attractive women at all.
First, you should know I am from small southern town of 15K, 80K in county. I am Protestant, conservative, yet like to have a good time and enjoy a good drink.
There are three or four categories that I see. First, there are those women who are condescending to men, belittling men no matter how sincere or how much effort they put into their relationship. Nothing the man can do is good enough. Next are the women that are high maintenance, highly demanding from a materialistic point of view - status seekers; snooty. Then there are some that look fine, are fun, but do not inspire confidence (trust) for the long haul, if you understand what I am saying. Finally, I am appalled at the percentage of women who take no pride in their appearance: badly overweight (I can take 20 - 25 pounds heavy) bad hair, bad clothes, etc. These are women that could look great if they just try.
I guess I am a bit spoiled because I was married to a beautiful woman for almost 20 years. But, again, it was attitude that destroyed our marriage. In a lot of these cases, it boils down to attitude.
