Installed Blocking App on Phone - Going to try NC or controlled contact

[nowwhatz]

I am getting the silent treatment which I know won't last so I have installed a call and message blocking app on my phone which also blocks my ability to contact her (set impossible to remembe pw and put away... .would have to make special trip to retrieve it).

This is the first time after a breakup that we have remained "friends" and maintain social media fb friend connections but I am sensing the "friends" thing won't work because, quite frankly, we don't like each other.

The next step probably will be to limit what she can see on fb and eventually delete/block her. I don't want to do that immediatly because I am trying to reestablish contact with her nephew who I like and also because him and I have discussed some business ideas.  I don't want her to poison that friendship.
