Prematurely called divorce busted, worse now

[Orich]

Tonight, my wife is going on a boat ride around Manhattan with people involved in this movie production that her old boyfriend that I mentioned started. There is a concert being performed on the boat. The band is managed by another of my wife's friends. The movie crew is there because they are considering using the band in the movie. I still have not confronted my wife about the text messages. I held my tongue last night, because every time I thought about bringing it up, I could feel my anger rise very quickly, and I was afraid to open my mouth. She is leaving straight from work, so I won't see her before she goes. My question is this, should I say something on the phone to her before she leaves? I don't know if talking on the phone is a bad substitute to being there in person, but I am consumed by this today, I feel like I am going to burst.
I want to ask her several things:
Does she want this marriage to work or not,
Is she involved with this guy,
Why so many texts,
Has she been physically involved with him,
What the ____ does she really want anyway?
And tell her that I am not comfortable with her going at all.
I don't know how much that last one will matter anyway; she says she doesn't love me, so why would she care how I feel about her going?
I know I probably should have said something to her last night, but I didn't. So now what? Wait until tomorrow when I see her again? I am upset and confused and still trying to do what's right, I don't want to make a wrong decision here.
Finally, should I wait and see how her therapy goes? I feel like it's a race against time now, considering there is someone else involved. I could have waited for a long time if she needed time to get better, but now that there is someone else involved, I feel like I have to do something now.
Thank you for reading this post.
