Should I ask this guy why he never wanted to have a romantic relationship with me?

We hung out a lot, we kissed, we touched, we shared intimate emotional details and sexted too. Even though he is terribly lonely he told me in no uncertain terms that we won’t be having a romantic relationship. And because I hurt him on one occasion inadvertently I’ve not been merely demoted to the friend zone but the aquaintance zone. Why do men kiss you but don’t see you as relationship material?
