Possible EA - sitting on the edge

[BWP]

It does make sense. When I call her on things she loses it. Tonight I walked into walk in closet to tell her something and she's texting on a new phone. I say 'is that a new phone' I was just curious. W says I had to get rid of the old one because you likely bugged it.

Here's when I think I blew it. I just said, why would that matter you have nothing to hide - she starts in about how she's not happy and it's my fault.

I said - I'm not responsible for your happiness. She goes on about how I'm a stalker and I listen to her phone calls.

She then says how she's not hiding anything she just needs privacy. I can't resist these statements so I think I need to do a better job of walking away. I had to answer 'there is a difference between privacy and secrecy'

Any suggestions on how to handle this type of thing in the future?
