Ex bf sends goodnight with a kiss emoticon what does it mean?

Anonymous
My ex bf and I keep in touch. One time we were talking and he sent a goodnight with a kiss emoticon. He randomly sends hugs and even an xo through text. I don't ask him why he does this and I know he has a gf although I don't ask. What does it mean when guys do this. I'm confused and I do still care for him.
