Relationships, especially long-term ones, don't get better with time but are kept intact by avoiding decline.

Married couples find contentment in other sources and remain satisfied with each other, and if not so, then the marriage breaks down.

There are four ways a partner response to something he or she doesn't like in the other:

1. Ignore.
2. Talk and find some solution.
3. Keep sulking while providing silent treatment.
4. Try to break up or start looking for other partners.

A new relationship that looks promising can make us think it will be happy forever, as we feel happy at that time.

A study shows that even after a couple of years the same people who were happy which each other show different kinds of behaviour, both positive and negative.

Negativity seems to be less of a problem in same‑sex couples.

Both male and female couples tend to be more positive than heterosexual couples when dealing with conflict, both in the way that they introduced a disagreement and in the way that they responded to the criticism, and they remained more positive afterward.

The “female‑demand, male‑withdrawal” is the most known conflict pattern in heterosexual couples.

This happens when women start complaining or initiate criticism and men respond by withdrawing.
