There is no basis for either one of you to evict the other absent domestic violence. If one of you leaves, he/she will be liable for lease default, just like the person who stays. This will not be worked out legally: the two of you will have to do it.
I think you should be free to act. However, if none of your notices to him were in writing, I suggest you do one written notice to his last address, including a deadline, and then sell if he does not respond.
The prior answer is essentially correct, but for one thing: the statute does not actually require your demand for itemization to be in writing. (Undoubtedly an oversight, but the language says nothing about written demand.) Written is better, but even if you simply gave the demand orally, you can go forward with the treble damage action. Since the common belief among LT lawyers and judges is that the notice has to be in writing, you might want to do a written demand anyway. But that tips off...
Based on what you have told us, I don't think the landlord can charge you for those things. However, there are specific statutory requirements about how to challenge the landlord. So I strongly recommend you see a lawyer.
