The drinking, OM, etc, are all part of the distraction. She's unhappy and uses these things to not have to face the reality that she is unhappy. She's lost and will ultimately find her way, whether it's all the way back to you is up to you. The amount of time it takes may take longer than you are willing to wait, and the damage done to you may too great, but if you are aware of the progression, it could help you hold out. In the end, it will be your choice as to whether you want a relationship with her or not.
I like what you said about the OM being the distraction. It really fits my sitch. When my W left she drank a lot, met OM, then started their R. She dumped OM & I pursued, which is why we haven't started piecing yet. She was lonely but didn't want to be around me yet. I had even gotten to the point where she sent me a text saying "we're probably not going to get a divorce, but I need to work on my issues first." I got that back in Nov, and took that as "green light", she wanted my company less and less, and then went straight back to OM. Another thing she told me was that when she left me drinking dulled the pain but not when she left OM. I pointed out that when she left me she had OM and he dulled the pain, and she still hasn't let the pain from the breakup with me come out yet. Of course logic has no effect on a WAS, so here I sit with W and OM engaged before our D. Time will tell how the rest of this unfolds.
