愛
A deep, tender, ineffable feeling of affection and solicitude toward a person, such as that arising from kinship, recognition of attractive qualities, or a sense of underlying oneness.

partly-overlapping stages of Love:

Lust, Attraction, & Attachment.

Lust exposes people to others; rarely last more than a few weeks or months.

Romantic attraction encourages people to focus their energy on mating; last about one and a half to three years.

&
Attachment involves tolerating the spouse long enough to rear a child into infancy; the bonding which promotes relationships that last for many years, and even decades.

The Side Effects of LOVE...

heartache

tears may drop easily

without love, humanity would die out.

P/S: LOVE me not because of Lust or Attraction...
