Marriage guarantees nothing. It takes Love, Respect, Trust, Understanding, Friendship and Faith in your relationship to make a Successful Marriage.  Here are Five tips for you extracted from Live Science.
Romantic love can stand the test of time if you apply elbow grease. In a study published in 2009 in the journal Review of General Psychology, researchers analyzed surveys of more than 6,000 people, including new relationships and marriages that had lasted at least 20 years. A surprisingly high number of people were still very much in love with their long-term partners, though the researchers drew a distinction between romantic love, which can endure, and passionate or obsessive love, which often fades after the beginning of a relationship.
The key to keeping that romance alive: hard work. Research has suggested these couples spend time and really care about the relationship; So for a good marriage, always resolve conflicts smoothly. 
Speaking of spouse driving one another mad, not to worry, some marriages actually thrives on negative behaviours only.
For some couples with serious problems, the best way to breed a happier marriage seems is by placing blame on each other, telling the other person to change, and being less forgiving and this is proven by a research on the topic by University of Tennessee psychologist James Mc Nulty.
Happy couples behave in certain ways that, rather than making them happy, may simply reflect their glee.
So ladies, if you have a partner who seems to be acting weird and get into blame game or demands for change then let me tell you that there are evidences which suggests that it can motivate partners to change. And don’t worry, its all good, just be tough to handle it.
Two words that can go along way. “ Thank You”. In 2007, scientists asked married partners and student roommates whether they appreciated the chores done by the other person. While most said they felt gratitude, many had not relayed these feelings to their partner assuming ‘ he or she will understand.” Results also showed individuals who felt appreciated by their partners had less bitterness over any imbalance in labor and more satisfaction with their relationship than other study participants did.
Another simple word that can boost partner pleasure: “ We”. A study proved that spouse who used couple-focused word such as “ We” “ Our” and ‘ Us” when talking about a conflict also showed more affection, fewer negative behaviour such as anger, and lower physiological stress levels during the disagreement. Using words that expressed separateness such as ‘ I”, “ You” and “ Me” during the discussion was associated with marital dissatisfaction. So ladies, it seems that ‘Thank You’ and ‘We’ become more important than “ I Love You”. So adopt this and have a Happy Marriage.
Sex is the ultimate remedy. If you have a partner who gets upset easily, often has mood changes and worries constantly. And that personality trait does not mix well in relationship and is more strongly tied to negative marital outcomes than any other personality type, No Worries, frequent sex could be the answer.

Money spending can be detriment of the marriage but not if you tie the knot with individual who has the similar line of thinking on money spending.
In a study of 1000 married and unmarried couples it was found that people tend to chose their spending opposites as romantic partners. The study showed that financial opposite has greater conflicts over money and lower marital satisfaction in long run than those whose spending tendencies were similar.
