If I didn't open DW's mail addressed to her, she never would have given a second's thought to tell me that: she was dropped from her graduate program, got dumped from her credit counseling repayment program (yes, for failing to make payments), had a money market account closed for making too many purchases, since federal law prohibits it. The only reason I found the multiple back taxes owed notices is b/c they also get sent to me.

Yes, I'm only here b/c of the children, but likely to stick it out with my low libido, shopaholic wife who will not take responsibility for any of her actions.

Still nothing from the OP, as someone said, the story may not be true.

I have to open DH's mail because he wants me to do it. He can't stand it. When I don't, it piles up and he throws it away!

If she doesn't have your permission to open your mail, it's a federal crime. So no, she doesn't have "the right."
