"For any man I am going to marry, we must date for at least 5 years"... Eniola Badmus

Eniola Badmus, popularly known as Gbogbo Bigz Girls, has said that she must date a guy for a minimum of  five years before she can even consider marrying him...this was exactly what the actress said in the interview:

 "What is the point if I marry today and tomorrow it's over? What's the essence? I am living my life. I will have a baby when necessary. Marriage is good but what's the essence of me getting married today and tomorrow I'm not in it? For any man I am going to marry or call my husband we should be together for five years before we walk down the aisle. We may have children but at least after five years I will know that you're ready for me. Not getting married today, and tomorrow he's out! I've seen it happen to my friends, I don't want to go through that trauma.

 My question is: How does a long term relationship determine a long lasting marriage?
