Is this a normal response to a 180?

I would just tell him that if he texts you in a respectful way, you will respond when you can but that if he sends you offensive texts, he will get no response whatsoever. And then stick to it. Set your boundary and stick to it.

I like this idea very much! But, perhaps I wouldn't tell it to him. Just do it. Respond politely to general inquiries, but ignore outright every single one that is crude or crosses a line or asks who you're with. He does not have that right. Remember that your rights to privacy are equal (or likely GREATER) than his "rights" to know anything about you. You are his equal at a bare minimum. But we all know you're actually his superior
