I think it is a relation of a life time. So we should choose our partner very carefully, so that there is no conflict. And marriage is not a contract, in actual we should marry only at that time when we we are sure that she/he is the one not to any boy or girl who is looking nice....And it also means to support him or her in what ever means possible..... In India we say that marriage is a ceremony in which two souls are combined as one.
