For me the song is about a person who uses one night stand to cover up for the loneliness he is feeling. However, at the end of the day he knows what he really longs for... companionship, love and support...
"This ain't love its clear to see" - a phrase used to hide what he longs for - LOVE. Because still, he is afraid of opening up for everything he is and everything he feels.
It's about a person who wants people to know that he needs Love but afraid to open everything about him because he is afraid of getting hurt too.
