The honest answer is that there is no precise number available from the outside without knowing the full details of the case, but the picture can be framed realistically based on what you have shared.
Two felonies and a misdemeanor is a serious charge combination. Family violence felonies carry significant weight in most states, and a violation of a protective order on top of it tells the judge that a legal boundary meant to protect someone was deliberately crossed. That combination is not viewed charitably by the bench.
The prior theft charges are the complicating factor the original answer correctly identifies. Judges look at the totality of someone's record when making bail and sentencing decisions. A pattern of prior offenses, even older ones, signals to the court that this is not an isolated incident of poor judgment. It suggests a person who has had previous contact with the legal system and has continued to accumulate charges. That history makes a judge less inclined toward leniency and more inclined toward holding the person pretrial rather than setting affordable bail.
On the protective order violation specifically, this charge tells the court something direct: that your husband was under a legal obligation not to engage in certain conduct and chose to anyway. That is a hard fact to argue around.
Pretrial detention without bail or with very high bail is a realistic possibility here while the prosecution and defense work toward a resolution.
On your question about visits and mail, that depends entirely on whether there is a no-contact order in place related to the protective order. If you are the protected party, contact of any kind while that order is active could create serious problems for both of you. Consult an attorney before attempting any contact.
