Please Give Me Some Advice I Feel Like My Bf’s Life Is Being Ripped Away

Back in February, my boyfriend was arrested on a series of charges that were falsified by his former business partner turned enemy. His old business partner is mad because my boyfriend didn’t want to give up his part of the business ( it is a dealership and he has a dealers license) and as a result, him and his gf who is a paralegal, went to the police and accused my boyfriend of selling a stolen car and falsifying that he had a dealers license. They pressed charges and even managed to get a warrant out for my bf’s arrest. My bf was arrested at an intersection that same day not knowing he had a warrant and not knowing what his business partner had conspired to do to him.

He spent 1 day in jail before being given a $50k bond. Fast foward to December and his court appearance is coming up soon later this month. He contacted his attorney to ask how his case was going and the attorney gave him the worst news we could ever imagine.

His attorney advised him to take a plea deal because his county had just gotten a new prosecutor and my bf will be her first case she prosecutes. She told my boyfriend’s attorney that she plans to go for the maximum sentence of 25 years if they decide to go to court. My bf’s attorney told him that because he will be her first case, that she is trying to prove herself by going hard on him.

My boyfriend can take the plea deal but it carries a $500k fine and 4 felonies on his record. He owns a variety of businesses and having four felonies would destroy him and everything he has worked for. We are beyond distraught because we are stuck between that plea deal or a possibility of 25 years in prison. We don’t know what to do. My bf’s old business partner told a lie and drummed up charges and now my bf will loose everything he has and we can’t do nothing about it. Even the people at the court have said that the guy’s story is missing gaps and holes but that bc nothing can be 100% proven that they are taking the guys side. I am so lost y’all. I am currently a student and have plans to marry my bf but our lives are about to udramatically change. He is going to loose his livelihood and live with a stained record. I love him because I know he has done nothing wrong and it pains me that our lives will be forever changed by lies. Is there anything at all that I could do? Literally anything at all? Should we hire another attorney or what should we do? How do we prove that my boyfriend’s old business partner is lying? Our lives are about to be ruined and I don’t know anywhere else to turn other than Reddit. If any lawyer has any suggestions please let me know. We have reached our ends and we feel so destroyed.

Update: he told me that he was initially charged with misdemeanors under the old prosecutor but when the new one went into office, she upgraded them to felonies
