I think that problem of women being unhappy after 30 if they arent married is more common in countries where the level of education is not very high. There is that stigma of she neva marry or she is a divorcee and it also more common amongst those who are not very financially stable, I think the question should be that should a 30 or more year old woman marry anyone she sees so that she doesnt remain unmarried all her life? Ladies in that category should look for love and not be desperate and if they dont find love, then they should concentrate on making the best of life and leaving a positive mark in this world before they move on, after all not all married women are happy in their marriages and if they were then they wont be cheating on their husbands. Generally, every body is different and there is no law that says all women should marry before 30 or at all.
