My guess is that most of the TMs (possibly all) were with EGF, but that she didn't want you to see the CONTENT of them because she was speaking freely and didn't want to upset you. She also may have TMd a nasty message or two to OM, who knows.
I'm not quite sure what you should do, but this is a good example of why "ANY contact is 'bad' contact" and why I preach 100% no-contact and transparency. NOP taught me that even when my daughters fed my wife BAD info and gossip about OM, it "fed the beast" and got her brain chemicals flowing all over again, and it reset the reconcilation clock back to 0:00 every time. It's very typical for a wayward to have an enabling friend with whom they converse all of the drama about the OM/OW, and it's destructive to the marriage. I always try to get the enabling friend behind the no-contact fireweall as well, if possible.
My advice to you for the next few days anyway would be the ol' "Do no harm." See if your wife's distant bitchiness is just a temporary mood swing and if she makes a move back towards you. I would NOT pursue her though! In fact, I'd do something that demonstrates my love via an AOS and then I'd back the hell off in terms of convos and messages.
