The lease for boyfriend girlfriend is the same as any roommates and married couples: all people signing the lease are responsible for rent. So usually it is not advisable to take anyone off the lease, even though one already left.
Of course there is exception, some state laws provide that domestic violence victim can end the lease early. But even that doesn't allow domestic violence offender off the lease.
In your case, there is no legal obligation for you to end the lease early for the departed tenant. When the lease ends, you have to return the deposit in a check that is made to BOTH OF THEM.
房客是同居男女，两人合签的lease, 最近闹翻了，散伙了，男的想把女的从lease 上去掉，问房东有什么办法？女的不工作，搞外遇，男的挣钱，交房租及时。
这种情况下，是不是女的不同意，房东什么也做不了？
看来房东不仅是掏粪，还居委会大妈啊
