Although there is a lot of anger, THX, you'll be fine. Keep in mind the bigger picture - there will come a time you won't stand any longer. Either that or she will return to the marriage and you will forget these times with a shrug and a laugh.
I agree, thinking of the future is a great idea. Taking your mind off of the current issues is also a great idea.
At some point you'll understand a little better why and what your W is doing. Compassion would naturally follow that. That comes sometime after the anger. If that helps.
