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

... or the Negativity Effect is a tendency most of us have to respond more strongly to negative events and emotions than to positive ones.

The Negativity Effect magnifies and distorts your partner's faults, whether real or imaginary.

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

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