As long as the payments are being made it shouldn't make a difference. Since your wife did not file, there is no issue with the bank communicating with her. Simply have her ask that they be sent.

I'm glad that you did not reaffim your mortgage obligation. The Bankruptcy Code does not require that you reaffim a mortgage obligation and, in my mind, it would have been very bad advice for an attorney to suggest that you do so because, if you fail to stay current down the road after your bankruptcy case is over, you'd still be personally on the hook to pay your mortgage note.
You seem to have a concern about getting monthly statements. This can be resolved simply by writing to the mortgage company and asking that it to provide statements to you. There are numerous techniques that a lawyer can use to persuade a mortgage company to issue statements to a debtor who did not reaffim his or her mortgafe debt in a bankruptcy filing.
