The 31-year-old actress said her relationship with husband Cash Warren has changed dramatically since they wed in May 2008 and became parents to two daughters, reported Daily Star online.
"Having time to see a movie or enjoy a glass of wine by yourself - let alone with your husband - before your kids head off to college? I know - it feels like an impossibility or a far-off dream. But I can assure you it is not...," Alba said.
The actress believes organisation keeps their romance alive.
"He... Takes over middle-of-the-night feedings, tends to fevers, and takes the girls to the park without me having to ask because he knows I need a break. All these things add to our romance," she added.
