What should I do if my landlord is trying to terminate my lease when I am not in substantial violation of its terms?

I rent 2 rooms & bathroom in a homeowner's residence. I signed a 6 month lease and my landlord is trying to terminate it after 3 months- I was verbally told last night I have 30 days. I am not in substantial violation of my lease and he cited differences in personalities and having to talk to me about issues (i.e locking deadbolt, turning off lights, and turning off a space heater when not in the room) and that he just doesn't know what he is going to have to talk to me about next. At this point I'd rather move but I am wondering if I am entitled to compensation or an expedited return on my security deposit since he is terminating the lease. Any advice would be greatly appreciated!
