Elvis - Can't help falling in love (English to Greek)

I'm attempting to translate this song with each verse in a different language. I've found translations online but I want to be certain they are accurate. Sometimes I see people translate to make it work when singing but that's not what I want. The translations in context are important to me. I have not been able to find anything online for Greek yet though. This is only one line I need translated though.
_______________
Wise men say only fools rush in
But I can't help falling in love with you
Shall I stay
Would it be a sin
If I can't help falling in love with you

Like a river flows surely to the sea
Darling so it goes
Some things are meant to be
Take my hand, take my whole life too
For I can't help falling in love with you

Like a river flows surely to the sea
Darling so it goes
Some things are meant to be
Take my hand, take my whole life too
For I can't help falling in love with you
For I can't help falling in love with you

I only have one more language and verse to go! The line I need I've underlined in the song above: Like a river flows surely to the sea.
Thank you so much for any help you can offer!!

Όπως το ποτάμι κυλάει με σιγουριά στη θάλασσα

Thank you!!!!
