Much as relationships are hard to build they are also easy to be broken. But in human life we only need three elements in our lives to keep a relationship going and that is love, trust, honesty, faithfulness. Once we have all those then our relationships are bound to last.
However once you are dishonest or have a dishonest partner the durability of your relationship becomes very minimal. And that is something that you never want to experience in your relationship. What if you are a very understanding person who really wants life to always work out with your partner because the two of have a long story behind you.
