Thank you.No. (And "to care for" in the romantic sense is now old-fashioned and rarely used.)
Thank you.mmmmm, Paul? Some people use the phrase "care for" nowadays to express affection. But "care about" is definitely far more common in expressing solicitous concern for someone. I say it that way because a real romantic feeling is not usually expressed that way -- it's polite, sincere, and mild, but that doesn't always add up to a romantic feeling. In fact it may signal the opposite of a romantic feeling:
"I love you, Alice! Don't you understand?
"Of course I do, Bobby. And don't get me wrong -- I do care about you."
