Has romantic love died?

It has become something of a fashion to say that "romantic love" is a thing of the past. Is it, really? And then: why do we use the adjective "romantic?" Does that suggest that there is nothing especially 'romantic' about love? Why must we use the adjective? Isn't love itself 'romantic'?   

Did cavemen fall in love? Was it 'romantic'? Well, it seems logical to assume that the woman's role in the love relationship was a bit more practical: having babies, raising them, keeping the cave as clean as possible...We might ask: was it love or necessity that kept the man and the woman together?  

Let's skip over, say, a million years--to William Shakespeare's time. Women were still under the male thumb, far from "liberated." And yet...how moving are the bard's love flights. Take sonnet number 145, for example, allegedly referred to Anne Hathaway:

"Those lips that Love's own hand did make

Breathed forth the sound that said 'I hate'

To me that languish'd for her sake;

But when she saw my woeful state Straight in her heart did mercy come,

Chiding that tongue that ever sweet

Was used in giving gentle doom,

And taught it thus anew to greet: 'I hate' she alter'd with an end,

That follow'd it as gentle day Doth follow night, who like a fiend

From heaven to hell is flown away;

'I hate' from hate away she threw,

And saved my life, saying 'not you.' "
