OP- your post in this thread claims he is your husband, the duplicate thread claims he is your fiance. Not to sound harsh, but if you cannot even be honest with a message board, you are going to have a much harder time, even with a thousand affidavits, getting this dismissed.
I'm going to assume that you are not married to this man because I've never heard someone refer to their husband as a fiance, but I've heard plenty describe it the other way around.
Non-legal advice: If you are not married to a man who has choked you in the past, and currently, cheated on you and you were afraid of physical violence enough to call the police, you need to run, don't walk, away from this man as fast as you can go.
Take it from someone who has been in an abusive marriage previously and now in a good marriage, that whole "every relationship has it's problems" spiel is just a way to make you feel better and justify staying with someone who is not good for you and does you harm. Working out problems and making it work costs way too much if the price you are paying is in fear, safety and blood. You are worth so much more than that.
On the legal side, as you have already been told, recanting puts you at risk of criminal charges of your own for filing false reports/false statements, etc. I would speak with an attorney - as in private counsel for you - before I would do anything to put myself at risk of arrest.
Next, the officers that were there can still testify to whatever they saw if there were any marks on you, whatever he admitted or implied, etc. Simply recanting may not be enough to stop a conviction.
And, the parole violation - that will be up to his parole/probation officer as to whether or not to dismiss. There's a lot of language that was signed and agreed to that the officer might still proceed on. It will be dependent on the probation officer and your fiance/husband's record with him on probation. If he hasn't paid his costs, fines, probation fees and done everything asked of him, the violation may include other areas and may not be dropped anyway.
Also, I highly doubt there's a quick fix to all of this. Even if you can recant and could somehow get a Judge to dismiss the new charge, you would still have to get the probation violation dropped (who knows if it's even the same Judge) before he could be released. He's rather likely to have a bond hearing long before everything else could be completed.
Bottom line: If you still insist on trying to help him in this situation, about all you can do to get him out is pay for an attorney for him to handle all these issues.
