I think that many people still do find true love.
As many now as ever did in 'the good ole days'.
The difference is that in the old days, nothing much changed in people's lives. Most people were born, grew up and died within 100 kms of where they were born. People didn't change much either.
Today, everything in our lives changes so much that the people we fell in love with a few years ago may be completely different people now.
If you both do not change at the same rate, or at least in complimentary ways, then the love will fade.
But it was still true love while it lasted.
So, yes, true love still exists, just don't expect it to last forever - and if you get 30 or 40 years, then count yourself lucky. (mind you, after 40 years, you may both be so blind and toothless that you will be stuck with each other for the remaining years of your lives !)
Cheers.
