<human>: Found the perfect house for rent for me and two friends, signed a lease in June. Wanted our friend to bring his girlfriend onto the lease (they would share a room), landlord was hesitant at first but agreed to re-sign with a slight rent increase. We probably should have paid more attention to his concerns..

A couple weeks ago, it came to light that their relationship has been shaky almost since the beginning of the lease and they were breaking up. We have wanted to avoid bringing our landlord into the situation, hoped to resolve it between the four of us, but she is being ridiculous. Snarky, passive-aggressive, keeps blowing off showings and house meetings, and refuses to budge on anything. She barely spends any time at the house as it is, as she goes to school a 20-minute drive away and often spends the night in that area. Our friend goes to school down the street from us and it makes 300% more sense for him to stay and her to find a place closer to school, but she refuses to budge and he is extremely uncomfortable sharing a room with her. (She "doesn't mind sleeping in the same bed for the rest of the lease and doesn't understand why [our friend] is making such a big deal about it.." You really think we're that stupid and don't see you're toying with him? Give me a break)

We have considered the possibility of the three of us "breaking the lease" and then once she's out of the picture, re-signing with just the three of us. Is it kosher for our landlord to accept the lease termination under whatever terms (keeping the security deposit, whatever he wants), give her (and all of us technically) 30 days to vacate, and then instate a new lease with the three of us?

Can you summarize the given text in a few sentences?
<bot>: Maryland. Fourth roommate/ex-gf of third roommate refuses to leave, is on lease. Can we terminate the lease, pay a penalty and re-sign without her without causing problems for ourselves/our landlord?
