There will always be troubles.

 Elder Bruce R. McConkie shares the following on marriage in his talk "Celestial Marriage" (New Era, June 1978): "When we as Latter-day Saints talk about marriage, we are talking about a holy, celestial order. We are talking about a system out of which can grow the greatest love, joy, peace, happiness, and serenity known to humankind. We are talking about creating a family unit that has the potential of being everlasting and eternal, a family unit where a man and a wife can go on in that relationship to all eternity, and where mother and daughter and father and son are bound by eternal ties that will never be severed. We are talking about creating a unit more important than the Church, more important than any organization that exists on earth or in heaven, a unit out of which exaltation and eternal life grow; and when we talk about eternal life, we are talking about the kind of life that God our Heavenly Father lives." 

As a member of the LDS Church I was taught and I also teach, that you should strive to be sealed in the Temple. In the temple we make covenants with our spouse and to our Heavenly Father. These covenants, when kept, bring about great blessings in this life and the life to come. One more thought I want to share from my reading this week is from Elder Bruce C. Hafen and is from his talk "Covenant Marriage" given in General Conference, October 1996.
"Another bride sighed blissfully on her wedding day. 'Mom, I'm at the end of all my troubles!' 'Yes,' replied her mother, 'but at which end?' When troubles come, the parties to a contractual marriage seek happiness by walking away. They marry to obtain benefits and will stay only as long as they're receiving what they bargained for. But when troubles come to a covenant marriage, the husband and wife work them through. They marry to give and to grow, bound by covenants to each other, to the community, and to God. Contract companions each give 50 percent; covenant companions each give 100 percent."
