"Xoxo"

I know that xoxo means hugs and kisses literally. But I'm curious if there is a message other than that when a guy texts it to you. My so said "goodnight xoxo" last night and I'm sorry pandering if that's a way of saying I love you? We've been together for about 2 years and haven't said those three words yet but I'm definitely feeling it and I want to know if he is too.
