Imagine that your s.o. continually speaks to you in a very abrupt and terse manner, sometimes barking orders or telling you not to do things. You've told him/her that you don't like to be spoken to in this manner and that you find it hurtful, but they keep doing it anyhow. What do you do about it? (Select as many as apply.)
Ignore it. There are other things that you like about the person so how important is this in the scheme of things anyhow? Just suck it up.
Keep telling them that you find it hurtful. Maybe the message will sink in eventually.
Bark back at him/her. Maybe by getting a taste of their own medicine, they'll get the message about how you feel and why you don't like it.
Give them the silent treatment until they get the message.
This is a deal breaker. If they person continues to disrespect you then the relationship is going nowhere. End it now before you have to spend a lifetime condemned to this kind of abuse.
