I literally was just speaking to a 34 year old girl yesterday who basically said young guys don't want to date older girls and older guys "date" but many are all just sleeping around and having a good time and not even necessarily interested in getting married.
Its a rough issue, I will tell you off hand, i'm single and lead a fairly productive life, my friend who is an attorney told me that I need to look for older women, simply because I want someone accomplished in life.
If you're doing 7 years to get a law degree or 11 for a doctor, you hit the age where you're ready in life to hit the ground running.
