My question involves criminal law for the state of: Wisconsin

What are the chances that all the charges will be dropped?
My ex-husband is now going to court for something he did in October against me. I had to get a restraining order because of it. What I want to know is what is a class A and a class B misdemeanor? The Class A misdemeanor is for criminal damage to property Statute:943.01(1) count 1 and the Class B misdemeanor is Disorderly conduct Statute:968.075(1)(a)Domestic Abuse count 2. He also has this statute:947.01 What does this mean by way of law? Also could the charges be dropped? Is it possible he'll just get probation? Will he have to spend jail time and/or pay a fine? The damage that was done is approximately $800.00- $1200.00. I rent my home and that is how much the landlords told me it was.Not sure which insurance company they use though, but they do have insurance. They want to make sure he pays for damages. He has no criminal record.
