That sounds very harsh
But it also maybe lacks some context?
Was this part of an argument tempers flaring maybe? Did you do something that hurt him and he said or did something hurtful in response?
It would seem a little unusual to care enough about someone to have a relationship with them but not care if you hurt them or not
So it is hard to imagine someone saying something like that if not in anger or out of hurt
If there really is nothing like that then that is not a relationship worth pursuing
