It's in what we call 4/4 time (4 beats a measure). However, it's really, really, really slow.
I've seen wedding couples do something called a foxy which is just a really slow foxtrot to this type of music. It's more of rock-back-and-forth-in-each-other's-arms kind of song in my opinion, and not really good for real dancing.
Some people will probably tell you to do some kind of night club waltz or whatever, but there really isn't anything interesting you can do to this song.
Just my opinion
