Breathe.

Don't ask your wife ANYTHING.

Buy and read Divorce Remedy, NOT Divorce Busting. It isn't helpful.

Do not print out or give her anything to read.

Be mysterious by going for a drive, to the movies (by yourself even) and don't tell her where you're going or when you'll be back.

And get some help for your temper. I bet that's one of her reasons right there. You need to be calm if you want help here, and for your marriage.
