Land Dispute With Brother

have a brother and we've been close friends for a long time. Our plan was to buy a property and eventually develop houses on it.
Location: New Hampshire
At the time, he was making about $90k a year and I was making about $80k. We bought a piece of land for roughly $300,000. The deed was entirely in his name and he took out the mortgage. I put about $33,000 into the property.
The property is 70 acres. Even though I put in $33,000, I only owned 10% while he owned 90% because he had the mortgage and had put in around $70,000. This year the property was logged and the timber was worth around $60,000.
While living on the property, I spent a Northeast winter sleeping in a tent and in my car. It was brutal. Looking back, I feel stupid because my older brother convinced me he could double my money in a year and I trusted him.
I'm 23 and he's 25.
As time went on, I got frustrated because he was making every decision. The direction of the project was constantly changing. One day it was one plan, the next day it was something completely different. During the winter we started arguing more and more, mostly over small things.
Over about a month, I realized the right move for me was to leave the project. During the summer, he had told me my share of the property would be worth around $100,000. Throughout that brutal winter I kept that number in mind.
I spent about a month thinking about it and planned to talk to him. My intention was to tell him I wanted out and discuss getting bought out by the end of the summer, which would have given him around six months to figure out what he wanted to do.
When I approached him, I was calm about it. I even started by explaining what I was frustrated about and talking about ways we could fix things. He had no interest in that. When I told him I no longer wanted to be part of the project, he completely flipped out.
I understand he was under stress because he'd be carrying more of the financial burden, and nobody was exactly ahead on bills, but I had tried multiple times to discuss getting my name on the deed and he was never willing to have that conversation.
He ended up calling the cops on me. I want to be clear that I was being cordial and polite the entire time. His only response was basically, "Get out of here." So I left and got a hotel with my girlfriend that night.
Since then, I've been staying with my parents, which has been pretty humbling.
I've tried talking to him about my money. First he told me he couldn't discuss it for six weeks. Six weeks later, I followed up and he told me he wouldn't discuss it with me at all.
Since then, I switched jobs and moved into a different career. One of the reasons I left my old job was to get away from him because he was my boss. About a month after I left, he got fired. He now blames me for getting fired and has posted online saying I ruined his job, that I'm a terrible person, and even calls me Satan.
Throughout all of this, I've stayed pretty peaceful. Honestly, I think I've been too peaceful.
He has also threatened to tow my car and claims he's receiving letters from the town about it, which I believe is a lie.
The only evidence I really have regarding my investment is a Google Sheet showing the breakdown of the payments. The important part is that when I told him I wanted out of the project, he deleted the sheet. Fortunately, I had made a backup right before that happened, and he was extremely angry that I had done so.
At this point, I'm not sure what to do. Do I sue him? Has anyone dealt with something similar? I'm mostly looking for advice on what my options are.
