Driving Wheels

i think it’s about a relationship …. the man and woman are in love [at least he ‘thinks’ he is] …. so he’s imagining / considering committing … but he always eventually just says ‘forget it, i’m not a relationship man’… ie he wants to have the girl but he can’t commit, he loves casual sexual relationships, he won’t commit to her even if he loves her. It’s a lost cause
