No, there is no "warning"
If you think that this may be an issue, this is usually a good time to stop trying to communicate with the individual.
If they choose to initiate new communications with you, they can do so, but it is usually a good idea to stop.
If you end up with a civil restraining order against you, this can have far reaching consequences beyond simply being told you can't talk to the person anymore (you can lose your right to possess firearms, this will show up on background checks, it will appear in future legal proceedings).
This is a very serious matter.
So if you think you are running a risk of "texting so much she is going to file for a protective order" - simply stop texting her.
