Possible EA - sitting on the edge

[BWP]

Puppy, I'm not sure but these are great questions.

I have evidence that they talk quite often on the phone through the cell phone bills but she'd say 'we are just friends'. I know I'm asking for a big smack in the gut but I want to know what those conversations are about before I'd be confident knowing what is going on. I would also want to know if/where they meet up. I guess I want proof or the absence of it.

Am I being naive? Are the phone calls enough to expose? If the worst is true and these conversations are inappropriate I want to know that so I can expose the EA. If the calls are just two old friends chatting then I keep DBing but figure out some different 180s.

I've read most of your input on these boards and I trust your experience and instincts so if you have any thoughts let me know.
