I think by government standard its like 2 years or something..but yes you need a court order to get it and for law enforcement purposes.

As for encrypting text messages..not really gonna work..here is why..if you use an encryption that is signed, the government can call up the signer and get it decrypted.

The only safe way is to use your own encryption for sending the message and the person on the other end must have your key to do the decryption. Not to mention you'll have to update your key every now and then because it can be compromised if used often enough.

Now as for his wife..he should just confront her directly..for all you know she is listening to "cheating" stories from her friends and just feels insecure..or maybe she feels like she is lacking attention..the longer he prolongs it the worse its gonna get...
