How do you block someone from texting you
Some phones have a built in feature in their phone where they have a list of people who cannot text them, if you don't have this you'll have to call your cell phone provider and ask them if you can block a number, if you can, it may cost money.
Just delete them off your little list and if they text you ignore them
or if you have a phone like ^ she said well you could do that
Get a new number.
if it got extreme, you could steal their phone and delete your number then put it back
