I rent a townhouse and sublease. My boyfriend move into the basement and is on the lease. We are now broken up and he doesn't want to move out. I was here 11 months before him then?

Confusing statements here - who is subletting?
If you and your boyfriend both have a lease, it doesn't matter who was there first. He is free to stay, you are free to move out as long as you pay the remaining months on your lease or find a subletter who is acceptable to the landlord.

If two of us are on a lease, can I have him removed from the lease once the lease is up for renewal?

Maybe depends on whether your landlord is willing.

ANY question on law needs to include your general locale as laws vary by area.
