Dump him or naw

Should I dump the guy and cut all ties with him if I’m the one always paying for dinner and buying him things and not the other way around what would you guys call this or describe this type of relationship as. And how do I go about this situation and fix it if there’s anything to fix. Should I talk to him about but always if I should I do I say it without a fight happening or say the wrong thing to offend him.
