Intimate partner love is three-fold; Passion (sex drive, craving for sexual gratification, linked to testosterone in males and females), Romance (the giddiness, mental obsession, desire to please and possess) and Attachment (the sense of calm, partnership, long-lasting security).
Attachment comes only after the test of time with an enduring and attentive partner, after numerous caregiving acts, trials of constancy and fidelity - each singular event evidence of deep affection for your well-being and thus earning your trust.
Many relationships never arrive at this juncture...having been kicked to the curb after the romance and passion (see above) has worn off.
