How to move out of your room in rented accommodation?

So, recently I have stopped talking more with my roommate as he has a habit of not sharing most aspects of his life and I tend to share more. Turns out, this guy also has lied to me on some trivial things (mostly trust issues I believe) and has gone out of his way to find new people to call home and share even less. Now, seeing all this, I don't wanna continue in that rented accommodation and I wanna move out to my home town ( my job is wfh type) but I was staying here due to my previous job location.

Now, I am not sure how to move out?

1. He owes me money, I believe I should take that before moving out.
2. He's choosy about who his roommate would be, so should I give him time to find that out? If yes, how much time should I give?
3. He had bought some items for the house, and I bought some, should I just plan to take those items back with me?
4. We have taken some items on rent, and those appliances are under my name for few more months. How do I handle this? If I cancel the subscription, we would have to pay more and then, I should handle the additional charge, right?
