How Long Must One Court/Date Before Saying "I DO"

I don't understand what our Nigerian men are up to these days o. Having dated a woman for more than 2 years, what else is left? Permit me to ask this in "yoruba english", You want to know her finish? Haba uncle?

But seriously, is waiting forever necessary? I understand those that don't have jobs, houses and all but even at that ehn can't you just do quick? Or tell me, do you prefer us proposing instead?...what a man can do, a woman can do better o...lol
