You may be able to sub-lease to someone but who would want to live with this loser. So I think you'll just have to agree to get along through the completion of your lease.
Ask yourself why you're bothering to love a guy who treats you with no respect!

Find someone online willing to take over the lease, or tell your bf that you're breaking up with him and go live with someone else and pay your side of the rent until you or he finds someone to take the lease.
