My Roommate's Wife Wants Me to Leave After Paying Rent

[Kingtemari]

I live in minnesota. i just started renting a house with my best friend his wife and 2 kids. i pay my share of the rent but my buddies wife and i got into an argument now shes trying to get me to leave. we just paid rent today ive now put in over a grand. she told me today that she called the landlord and told him i started a fire in my room. she then gave me a hand written eviction notice and asked me to sign it i told her i wasent leaving or signing her eviction notice.
she told me if i didnt agree to sign it she would call her friends and have them testify against me. will she be able to evict me if her friends back up her falshood without solid proof?

It will be up to a judge to determine whether, after reviewing all of the evidence, her allegations are credible.

Are you on the lease or not?
