Is this the end of my marriage?

[P17]

WAS called me earlier while I was with my dad. Didnt answer and she didnt leave a message. I thougt I had blocked her calls but obviously not. Adjusted software on phone so they should not be hung up on (this is how the software does it).

Yet again W ignores NC letter by calling me direct instead of IM and by contacting me at all. Not sure when she will 'get it'. I had her down as semi-intelligent. I was wrong about that and so much more.

I thought I would be the one to break NC letter, not her!
