Guys, a male friend recently kissed me on the neck when we hugged goodbye. Is he interested in more?

He walked me to my car, we hugged... and for some reason hugged a second time and that’s when he kissed my neck. We’ve been friends for a while but up until recently have never been single at the same time. Is it just wishful thinking on my part or is he signaling interest?
