My question involves criminal law for the state of: Ohio

My question involves criminal law for the state of: Ohio Criminal Code and Traffic code.

Here is my story; back in Feb. my fiancee used my car, which is registered to my mother and insured by my mother, used my car, with his license suspended to go with his cousin to break into a house, me not sure of why they took the car in the first place, had I known I wouldn't have let them take the car. The cousin was arrested for Burglary and other stuff that has already been bound over to the grand jury. He left the scene in my car, and actually was seen driving away by a responding officer with a dash camera caught the registered plate and called my mother to see why the car was down there, (smart police work) - props there. in the mean time, he called and told me what had actually happened, and said I needed to tell the police I was driving and drove home, picked me up and went back to the city. Where we were at the police station, I we were both read Miranda, and I wrote a statement basically stating I was driving the car the whole time, then they told me about the dash cam, and I had to retract my statement, well, I had to write another statement below my original one first stating the original one was false (they made me write that), but not him, they gave him a new report to fill out, and I was given a ticket for Ohio Criminal Code 2921.13 A-3 which after some research says it had something to do with firearms? wouldn't this be considered perjury? and a ticket for wrongful entrustment Ohio Vehicle Code 4511.203 at my arraignment I plead not guilty to both charges and awaiting my court date. He was given a ticket for the same 2921.13 A-3 and driving under suspension, and plead guilty to DUS and not-guilty to 2912.13. Our court dates are on the same day and within a half hour of each other, I don't want to see him, and want a different court date. Should I ask for a continuance or call the prosecutor and speak to her before the court date and work something out?

This all happened in the city or village of Geneva on the Lake, Ohio through lake county municipal court.

Questions:
1. Can I actually be charged in the Burglary or as an accessory as the police said I can be. and will I be notified of such or an indictment?
2. In the court dockets it says "obstruction of official business" and not falsification as my charge can i get a lessor charge or have it dismissed or something like that?
3. Since this incident, I have broken all contact, changed my phone number and blocked all internet access with my now ex-fiancee, and have a Temporary protection order and a police report filed that he caused and threaten to cause bodily harm to me, and is now sending message to my friends regarding my safety, what I can I do about this? -His record is an arm full, you name it he has been convicted of it. Including a recent M-1 Domestic Violence Conviction, he was a bad decision. Only reasons I was with this person was from a recent incident over the summer, that resulted in the loss of a pregnancy. He knew i Was vulnerable and took advantage of me, and I didn't see it until now.
4. Should I really get a lawyer? or Public Defender?
5. I want to have the book thrown at him, I want my life back and want to continue my journey BACK into medical school, this will destroy my career
6. Can they take my car, what potential sentencing am I looking at for everything?

If I want to plea to lessor charges, any advice as to what I should consider?

-Any and all advice would be great- Thank you Expert-Law
