There are things in life that can not be reverse back to normal. Somethings in Life feels great when seeing from outside but when you get inside it is really different. Marriage is not like we see in the movies or in the story books. Is not a fantasy but real deal, people get wrong ideas about marriage and expect thing that are not real so they follow love and sometimes pressure and end up sadly in the relationship after been couple. Lets prepare to face reality than fantasy love and wishes. Be prepared to sacrifice and face real life deal. I am not really good at this but at least this is what I can say about this words.
Be prapared to face reality of marriage before you accept the ring on the finger. There should not be Should I Know from you.
