Most couples these days are unable to have fulfilling and long-term relationships because of many reasons:

1. Couples get into the relationship too soon without knowing each other completely and when this relationship is only based on initial attraction instead of spiritual and emotional connection then eventually it fades away.
2. Lack of accountability: People fail to take accountability these days. Everyone is too busy to blame and see faults in the other person instead of owning up to their own shortcomings.
3. Lack of common values: A relationship is a long-term thing that involves lots of ups and downs, so there must be a lot of shared mutual interests in order to keep the relationship going otherwise with time it loses its spark.
4. Lack of trust: Trust and respect should be the core values of a relationship. A lack of trust and respect causes the relationship to fade away with time.
5. Emotional intelligence: The emotional intelligence of a person has to be strong before getting into any relationship so that whenever a situation arises, they can try to fix it through a lens of love instead of viewing it through their own emotional trauma.

Having a good relationship is not a tough job. No doubt, it takes a lot of mutual effort, understanding, respect, and love. However, if two people love each other deeply and are willing to stick with each other, then no matter what the situation is they can easily navigate through it.
