If a guy puts kisses on the end of texts to other people but you, does it mean he doesn't like you?

There's this guy I know and when I was talking to our mutual friend group it came about that he puts kisses at the end of texts to them but he doesn't do that when he's texting me? Before, I had the impression he could like me but now I'm second guessing it.
