Overnight guests

What is a reasonable amount to have a partner over when you have a roommate because my lease says no more than 3 consecutive nights and I followed that yet my roommate complained so I lowered it to 2 nights a week and I’m still getting complaints. For context we are always hanging out in my room my boyfriend only comes out to use the bathroom or get food. I’ve tried to clearly ask her for a concrete issue so I can address it if we are being inconsiderate but she literally just had nothing to say. Is 2 nights out of 7 days too much to have a partner over because I’m on the verge of just telling her to fuck off I signed up to follow the rules on the lease I signed not extra ones she makes up when she’s not even the landlord
