Separated Therapy and No Change

[Arcola]

I do its in Infidelity/Extramarital Affairs named To Pursue or Not #2. I haven't mentioned it there, only to my IC which happens to be one of DB's.

So here's a little more detail
-WAW has/had EA, I don't know if it was PA
-Pretty much been a doormat for WAW and we're S as of Dec 2014
-Since bomb drop, we've been friendly, small talk throughout the day via emails, doing things with kids, etc. but no intimacy or talks on improving situation
-On a 3-day trip with the kids in May, I get a hold of her cell phone and she's met this guy at her 2nd job and they text each other alot, and he's been over once but she fell asleep (nothing happened), some of text exchange is sexting; she referred to me as her ex in texts to him
-On way back home from trip I confront her about it, she said nothing happened along with how it just felt right, and they don't talk anymore, plus he's in another country now
-I decide to go last resort technique and all the friendliness between W and I goes away too

***Note***
Through Facebook snooping this past month I highly suspect she's got an EA going on with one or two OMs and I can only suspect its probably PA.

So what actions should I take to get back that friendliness from her? I thought she was growing warmer towards me despite finding out about OM2. Or should I continue on my last resort technique as well as GAL, etc.
