Unsureman...
I hope you are doing OK.
I wanted to comment on a few things.
First of all, you said that you have always spoiled your wife, but you said that after kids were born, you "allowed" her to go out once a week with her friends. Allowed her?
Now she seems to have acted out repeatedly right in front of you. Is it possible that in the past you were controling of her? (Not that it would in any excuse her behavior if you were.) Maybe when you said you "allowed" her to go out - maybe you meant that by watching the kids, you made it possible for her to go out.
This is commendable of you, but I would also say it is also not so much" above and beyond". Having been a SAHM for many years, it always baffled me when a working H thought that it was an act of generosity to watch his own kids while the mom got out of the home periodically. Maybe I misunderstood the way you phrased that.
I also want you to know that IMHO you place too much importance on your looks, your physical stature, your income, etc. Not to say that you are boasting. But your WW's actions would be unacceptable if you were a short, fat, unattractive, poor guy. Marriage is marriage. Commitment is commitment.
My H is severely disabled, and in a way that makes his body what I am sure would make him unattractive to many. But that would not be any justification for me to betray him.
And, finally, I am wondering - if you feel your wife has hacked or somehow otherwise has access to your phone - why you haven't gotten a second phone? And is it possible that she has placed VARs of her own? I never saw a response to how she knew you had set up your VARs.
I think that we sometimes think if we are behaving in an admirable way, and our spouse betrays us, then we should get tougher, try to control, etc. i know I did. But I feel we should behave in our relationship in the way that feels right to us. And if we determine that we can no longer stay in a relationship with a partner who is doing x, y, or z, then instead of modifying what we believe to be right, we have to make the difficult decision to stick to our standards.
I hope your holidays went well, and that you are able to work through this terribly hard time and come out on the other side - with your integrity / standards intact - whether together or apart.
Please keep us posted. We care about you.
