He might have lost some privileges and didn't cancel on his own, OR, the facility might be on lockdown and all visits are suspended for awhile

If you are relaying messages from your inmate to people on the outside that further commit a crime on the information you passed, then you could be looking at some serious charges. If you are making calls on behalf of other inmates, it's not a crime but it might jam up your inmate or others inside for circumventing the rules if they somehow find out.

She is a captive audience at the moment, so to speak...;) All you can do is be yourself and take your best shot, you won't have a better opportunity than right now when she has time on her hands.

That might also be referred to as a "conjugal visit" where a spouse can have a sexual encounter with their related inmate but this is only available in four state prison systems, California, Connecticut, New York, and Washington.

Inmates need hope. The hope of something better or different than the life that led them to the charges that sent them to prison. If you know what their interests are, you could introduce them to magazines and/or books that are mailed into the facility from the publisher. You could write them uplifting letters.

You would know your husband better than we do. But, it's not easy to cheat from jail. If you suspect something, your instincts are usually right. Only time will tell.

Conjugal visits are rare these days and there are still a few state prisons that have them. Currently, only California, Connecticut, Mississippi, New Mexico, New York, and Washington allow conjugal visits.

All you can do is continue writing letters. Some inmates, especially newly incarcerated ones are affected by the harsh disconnection from society. They might be "in their feelings" and are not ready to communicate with people on the outside just yet.  If you are persistent, the letters will eventually make an impact and she will eventually respond.
