200 percent ....TRUST is a very important factor for all relationships. When trust is broken, it is the end of the relationship. Lack of trust leads to suspicion, suspicion generates anger, anger causes enmity and enmity may result in separation.
A little girl and father was crossing a narrow bridge in a turbulent weather . Father told daughter to hold his hand ... no , you hold my hand ... father was surprised ...what's the difference ? .. you will never leave and let my hand go ....that's trust

And what is the alternative ? Doubt ? When you doubt your power, you give power to your doubt ...There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills and a make a mountain of distrust.

Doubt can keep us up awake all night long, but trust makes one fine pillow to sleep

Spouse is life partner.

If there is no trust they can't live together.

Both has to mutually trust

As much as we trust ourselves.

For a permanent relation we have to trust them 100 %.Relationship is based on trust n understanding.

Good question
