hi miriam-go,
I am sorry you are going through this.
Just curious, do you read the texts? I talked my husband into blocking his daughter's (my stepdaughter's) texts. It may have been the best decision I have made

In a real emergency, her husband can text us. Or she can borrow someone's phone. But it is a clear boundary that we don't want to get this sort of texts from her.
I'm not sure how old your daugther is...perhaps you can give a few more details, as this may be way off in your situation.
