If you have never been married by age 30 is there any hope for you?

Of course, your a late bloomer, lol. You will find you're prince charming.

My mom found a man at 40 never give up

It is better than marriage at 25 and divorce at 30

Yes, there is. My uncle was married at 43 and he is leading a good life.

Never give up on love as the proverb said '' never give up on love cause it may knock on your door when you least expect it!!!!

Yes

Age would only be an important issue in marriage,should a woman be thinking about childbearing.

Sure, marriage is just an idea, and agreed upon concept.
It is nothing you should ever judge your self worth on.
