I'm going to tell my roommate I'm planning to move and then once he finds another place I'm going to say I changed my mind and then find another roommate.
Why would want to do that to your roommate? Do you not like him?
No, I think he's annoying and don't want to be around him anymore.
Its wrong to lie about moving. You should be honest about the situation with your roommate.
Nah, my plan is much better.
I really think you should just tell him that you don't want to live together anymore, because lying to him is much more trouble. If you explain the situation to him I'm sure the two of you can work something out.
