Happily Separated

So, I have been trying to get happily separated! I bet your like 🤔? What does that mean? "Happily Separated?"
For most people, who have taken all that they can take in a relationship, finally come 2 a point where they " Call It Quits" & just "Break up".
Well in my case, my marriage has been over 4 me for over a year now. I have constantly voiced my opinion, 2 my ex, that " I am so over & done with arguing, everyday, literally all day long". I have also said to him on a daily basis that "I want to be by myself"!

I am @ the point in my life where I just want 2 be "Happy" & "@ Peace"! I definitely don't want to be responsible for nobody else's happiness but myself & my kids! I don't have the "energy" or the "want to", to argue deal with any drama of any kind. 
Most importantly, I don't feel the need to live up to anybody's standards of how I should act, what I should do, or how they think that I should live my life, in order to make that person happy!
With that being said, here is my problem....
My ex knows how I feel & he knows that I want to be by myself because I tell him constantly & on a daily basis. 

The problem is that he refuses to let go & leave my home😭, that I paid for!

I honestly DON'T want to be in a relationship with anyone. I want to be by myself. 
You have absolutely no idea how truly I "WISH" 2 be " "LONELY"!
Lonely for me is PEACEFUL. 

It has gotten so bad that I want to leave my home, that is paid for, & pay somebody rent, just so that I can get away from him bc I know if I don't I will be absolutely so miserable to that point that I seriously consider suicide bc I feel that it is the only way that I can get away from him & finally be in peace. The only thing that keeps me from doing it, is because I don't know what my 16 year old daughter will do without me because I am her only parent. Her biological Dad died, from driving & driving, not that he was ever in her life, bc he made the decision to be an alcoholic instead of a Dad.

So, what is there to do when you can't physically make someone leave your home?

What do you do when you make a decision for yourself but the other party refuses to leave or give up?

What do you do when someone refuses to except that the relationship is over?

The only thing that I can come up with is to leave my own home. The only problem with that is that I have no transportation.

I feel absolutely stuck & hopeless.
