So back with an update and question.  

I am wondering what technology is best to block calls, text messages and voice messages.

A little history.... There used to be a service through our cell phone company that blocked all calls/texts and voicemails.  The service has been discontinued and now we only have what comes with our cell phone. 

We have come to find out that you can hit block from the phone and it blocks text messages and deletes them however, while it stops the call from ringing it lets the caller go to voicemail.   We also have learned that even though these numbers are blocked, and we do not receive the message that it still shows on the phone bill so we know how many there are. Which is a scary amount for someone who never receives a response.

It is a 15 year story so I guess I will highlight it a little ... 

My husband has a crazy ex who has harassed him for years.  

She never contacted him about the kids where she didn't have to start out the conversation by calling me a B**** or some other name. We have been up and down the roller coaster a bunch of times through the 15 years we have been together. The kids were 11 and 13 when we met so we tolerated it out of respect for the kids. So when the kids both were 21 we blocked her from my husbands phone.

That did not stop her. She called from her work, she called from other peoples phones, she would go into Verizon stores and uses their display phones to text, just constant harassment!! We should have called the police but the kids were young and out of respect for them we didn't.

No one ever calls her back …. well normally ... 

So last month she called from someone else's phone making it seem like an emergency and husband believed it and called her back.  Well it wasn't an emergency and he is sorry that he did.  

At this same time they discontinued the service that blocked her.  She started texting him and calling him all the time again.  He never answered the phone or the text.  So he got a new phone so that he can block her.  Now only to find out that it doesn't block everything and she doesn't seem to know she is blocked.  But seriously what sane person texts someone constantly that never responds?  It also shows that in the 7 or 8 years that she was blocked she must have tried all the time to see if she was still blocked.  

It always starts out the same as things do with any CRAZY person.  First she is friendly just about the kids (whom are adults I want to point out) next she starts sending him pictures and trying to reminisce with him...  Then when she gets told to stop texting and calling that is when she snaps and starts the even crazier behavior.  Each time that happens she goes a step farther and last time was trying to get to me.  

So my questions ... 

So anyway first is there an app or technology that we are missing that would block all of it?

Second my thinking might be if we can get the calls blocked or even if we can't, ignoring it is a lot easier when most of it does not come to his phone.  Meaning, if she doesn't know she is blocked and just keeps sending messages to limbo maybe that is less escalating??  and prevents her from snapping and getting worse again??

However am I wrong in thinking that anyone in their 50's who acts this way is a threat?   meaning this is sooooo not normal behavior.   We have a whole folder from over the years of texts messages etc. and there is no reason for her contact him so if her text messages are non-threatening and just annoying right now  can we still do something about it?  She has been threatening and as recently as last summer.... Advice???
