Advice on possible EA

[Greek]

I dont want to get into the whole story about how I got to where I am just yet but presently it is as follows

At some point, though, the whole story is going to matter. But first....

Her attitude is that she needs to find herself again and has this huge journey she needs to go on to rediscover herself. That person she says she lost during our relationship

It happens.

Found messages on facebook to a friend she met at a previous company about 7yrs ago. At that time we were temporarily separated too (but not married yet) she did admit she was attracted to him at the time but nothing happened between them (she said she was attracted to him because he looked and reminded her of me)
Messages were not suggestive, but she did go into detail about our situation and how she is on that journey she is always going on about lately. This bugs me as I feel that she shouldnt be telling these Male "friends" about our troubles and then exposing her weaknesses to them (the journey thing)giving them all the info they need to push her buttons - - cue sensitive deep caring male type

You are correct. She should not.

Found texts on phone from a work friend. she has spoken to me 1 or 2 times about him and likes how “deep and philosophical” he is. But he supposedly happily married with 2 kids, and 13 yrs older than her. I was not comfortable with the endearing terms he used in his texts.

Correct, again.

My concern is that she is very vunerable right now, and anyone taking advantage of that will just end up messing her up even more.
My wife has always had a good head on her and I dont think having an affair is something on her to do list, but in her emotional state she is easy picking for some supposed "deep soul just looking for friendship"

What has she been missing all these years?

Sounds like she is having an A to me...or just about to.

If you have solid proof, confront her and draw the boundary.

But you still MUST grapple with the question of what she has been missing. Even if she is not having an A, she is throwing out all kinds of lures...looking for something. What's missing?
