Yes, but don't get yourself worked up over it all.
Here in my state there is legislation pending to award an aggrieved spouse who has had adultry or abandonment committed against them more than 50% of the marital assets.
But my experience(new as it is) is saying get the info then let go of it. Others may advise against it but I think it is about what each indiviual can take.
So, Yes protect yourself with the info but mostly by taking care of yourself, mind and body.
