Wait...Does This Mean...?

Just finished watching an old (1951) mystery movie on Netflix - typical innocent man framed for crime, on the run, etc. Only two people will help him, and older man and a (loose) woman. 

I like these sorts of old movies, so it was fun. And then at the end, when the crime is solved and his innocence proven and we're ready for the big Happily Ever After...

HE GIVES THE WOMAN A WRISTWATCH AND GOES OFF WITH THE OLDER MAN.

And I'm like: Wait... Wait.... Did that just happen? The woman got a practical gift ... and he's going off to live on the isolated desert ranch with the older man? What year... 1951?! I didn't know you were allowed to end a movie like that in 1951.

I'm still amused.
