Shall We Cross That Bridge?

"When we get to the bridge, we'll cross it"
Why do people say that phrase?
Why is it so hard to admit our likes and dislikes and lay them bare to others?
Not forgetting that there is no perfect person, but there are some issues that are simply non-negotiable for some people.
Marriages of these days, I dare say, fail because the partners refuse to address the inherent defects in their partners before going ahead to get married.
People tend to think they can change their partners after they marry them.
A lot of people see their partners exhibiting some behavior that they know they simply cannot live with and yet, they keep mum about it. Many do this because they do not want to lose the other person and so, they think to themselves, "let us get married first, then I will complain about it..."
Let me opine here, if you do not complain about it before you commit yourself with marriage, you may never be able to complain about it with effect.

You see that your girlfriend cannot cook and clean and yet, you do not encourage her to learn before committing with marriage. You marry her and start complaining that she doesn't cook your food and your house is always dirty. Then she tells you, "you saw the way I was before you married me!"
Or you know that your fiancé is fond of getting drunk and carrying other women all over the place. You fail to make a stance on it during your courtship and you think to yourself that he will change after marriage. That man may never change.
You boyfriend is fond of ripping you off for money and you take care of the basic needs of the house and you think it's going to stop after marriage?
Your man does not encourage you to pursue your dream and you think that he will encourage you after marriage?
You girlfriend does not want to see your family and you think she will fall in love with them after marriage?
Your boyfriend slaps you around and beats you up and you honestly believe he will stop after marriage? You have successfully worked your way into an abusive marriage!

The best way to avoid conflicts in marriages is to address these 'silent' issues before going ahead with marriage.
I'm not saying we cannot change our partners after marriage, but then how do we go about it?
It is a known fact that some people are so deceptive that they do no even reveal their true colors until after marriage.

Do you also say that you will cross the bridge when you get there? Have you gotten there yet? Have you been able to cross the bridge without hassles?
