The only way to find out is by asking your fiance. The inmate's privacy is protected. There is no disclosing how much money is on their books, how much phone time they've used, who is putting money on their books, who they are talking to, or who are visiting. 

It is true that an inmate may file for divorce if they someone on the outside handling the actual court filing. The petition can be notarized in prison, and then that document must be filed with the family court in your jurisdiction. There is nothing to this that makes it "faster", but if you are sitting in prison, time is not a factor as you have plenty of it.

As an inmate, you treated like anyone else. What goes on the outside is the same as the inside. If you treat others with respect, you will, in turn, get respect. If you mouth off, you're gonna get your coconut cracked. 

Probably the hardest part is getting used to the fact that everyone you know on the outside (mostly wife and kids) are living their lives while you are locked up. You have absolutely no control over anything. It feels like you have died and are watching your loved ones live their life and you cannot participate. Your mind plays tricks with you, you lose faith in your relationship, etc.

write them a letter, it will get the ball rolling

Obviously, there are no statistics on the subject, but if it is like the other women's facilities, there are definitely relationships that turn sexual. It is more prevalent when the sentences are lengthy. Women with long sentences will look for a partner to ride their bid out with. If they have partners, than the sex would be often but it can't happen in the "light of day" as it is against the rules. And, this is not limited to women

This is not going to be easy on either of you. He is thinking you are seeing other people because he can't see what you are doing. The mind plays tricks and you feel desperate. Connecting, communicating, visiting, talking on the phone, writing... it's all you can do. Do as much as you can and hope for the best. You might do everything right, never run around and he still might not come around. Good luck!

Inmates in a halfway house are permitted to leave for work, treatment meetings, church and short trips to the store. Obviously, if they are out getting employment, they are going to run into people on the street, women, too.

You know better than they do for sure. Listen to your heart only!

unfortunately no. inmates have a right of privacy from anyone peering into their personal information while incarcerated. The inmates are afforded privacy as it relates to their visitation list, their phone list and who is putting money on their commissary. The only person that can tell you is the inmate themselves. Use your instinct and good sense.
