I actually disagree with blocking the texts. I would ask what was her real intent for sending them though, and was she really telling this to you or to herself. I would just detach as best you can and delete any negativity from your memory banks along with the text message. I could see blocking texts and emails as controlling from her perspective. My W unfriended me from FB but must have forgotten she gave me all her passwords several months ago. I've checked it a few times even though I know I shouldn't and haven't found anything on there that bothers me so I'm sure it was just another space-creating thing for her. I know she did accuse me of blocking her emails a few weeks ago and seemed really ticked about it, but I explained my account had been cut off due to cutting off the cable. She didn't accept that answer, even after it was reactivated when we had the cable turned back on.
But, yeah, the problem isn't the text messages it's how you respond to them. She'll always find a way to hurt you if you give her the power. Blocking one method won't make it stop.
