we know that the inmates love getting mail. if your inmate is new to the system, they might not be totally settled or maybe they are in their feelings at the moment. We would recommend that you continue writing if you are able.

Not unless your inmate friend were to tell you. It is most likely some sort of incident report, BUT the privacy of inmates is their business on the inside and no one else's, just the same as it is for you on the outside,

The question is why would you want to continue in a relationship that requires you to take a beating of any kind? Hopefully, they keep you away from him so that you can move on with your life. There are millions of guys that you could kind that won't ever think of hitting you. You should explore this new "freedom" and stop going back.

If you are referring to YOU having sex with an inmate, that is not going to happen as there are no prisons that have conjugal visits any longer. BUT, it can happen - I was in a federal camp and there were two or three guys that had some arrangement with the guards that gave them a broom closet to have sex in the middle of visitation. If I didn't see it myself I would have doubted the story. I also

We would say that 1/3 to 1/2 have engaged in some sex with other inmates, but less than 5% that would have it with the guards (that is a felony where the guard becomes an inmate)

If the letter did not get sent back, he definitely got your letter. Since we don't know what is going on in the relationship, but we would encourage you to keep writing and see what happens. If he is a little angry, give it some time. I can tell you for a fact we love every piece of mail that comes in, even junk mail LOL.

Why would he lie about this, in order to stay in an extra month? Sometimes the inmate release date changes slightly for a variety of reasons. If he is lying about this, it might say something about the relationship

The only way you'll know is if your inmate tells you. You cannot get a copy of or information regarding to any of the inmate's visiting list, call list, commissary spend, or people that send your inmate money or mail. Believe it or not, inmates have a right to privacy just like you.

Not going to happen. The inmate is entitled to full privacy - their visitation list, call list, commissary money whereabouts, and what was spent are fully protected. 

Unfortunately, you already know the answer to this one.  Your loved one is still using and no matter how they appear most of the time, those unexplained absences are explained when he violates (as a result of a UI or other tests). The only person that can change is the person using - they have to want to change or nothing will change.
