The most important component of any relationship is trust. There are many kinds of trust needed for a marriage to be successful. Any other wordly thing can be brought back once it is gone, but trust can never be reconstructed. In fact trust can be said to be the very foundation of any relationship. Here are a few kinds of trust needed to make a marriage work.
Physical- Physical love is one of the most important components of a married relationship. Two people get into physical communion after marriage. And a trust that they shall not look for physical favours from some one else other than their partner is very important. This also defines how much they truly love each other. Love is possessive and the fact that you are in another relationship for physical favours cannot at all be tolerated. So you need to build trust in the relationship.
Spiritual- Love can be platonic only in the novels. But a trust in marriage like you would only love your husband or wife is very important. Now no no one knows what is going to happen tomorrow. If you love your partner only for money or looks then that is no love at all. Hence a trust is required in marriage by which one is assured that you will never leave the side of your partner, no matter what happens.
Monetary- Among the many kinds of trust needed in a marriage this is one of the most important. Try to build trust in your relationship by which your partner is assured that you are not going to squander his/her money. There are many couples who love each other deeply but cannot trust each other on monetary issues. Hence it is important that you build trust in the relationship and learn to save and invest money in the proper way.
Familial- A trust in marriage regarding familial issues is also very important. You need to take care that your partner is assured that you will love and care for the rest of the family members as well. The more you love and care for your partner's family members the stronger will be the trust in your relationship.
Support- Another kind of trust most needed in a marriage is the belief that, "I am by all all the time, no matter what decision you take." This kind of a reliance your partner must have on you. And this is important for your relationship to blossom further.
Try to incorporate all these virtues of trust in your relationship and let it usher happiness.
