Relationship problems. Ending it probably.

So im not going to write whole lot because im typing from phone. Me (29) and my gf (29) have been together for 13 years. We have a child together whos also 13 now. Yes young parents. But basically the relationship has gotten to a point where i think we can overcome this. Most of the relationship ive been the one holding it all together. She was sick. We didnt know at the time why. I always wasthere for her. Going school, work, i took care of the child and household. This was for 6 years straight. She was horrible to us, yelling at the morning that we shouldnt talk when i get my kid ready for kindergarden or school. Because she wanted to sleep. She was very toxic at us calling us names and adhd retards all the time. Fast forward. I planned to move out like 2022. Suddenly she started doing things. Before that child services were also contacted because when i was at work my kid told the school that mother had hurt her. So i found another apartment. But i didnt tell her exactly why i was doing it. She definetly suspected im going to leave her. But after awhile i started feeling guilty, i started questioning myself, am i the bad person? So i let her back in. She was still toxic. We had a worker who came home and helped us with family things. She twists all the storys like im the bad person. Fast forward. Now she goes to gollege and im at home again. Felled into deep depression. I left work. At work i kinda liked one girl. She found out. Nothing happened but the way she found out was going thru my phone. I was talking somebody on the knternet how hard its been. And that this girl at work sees me as i am. Well ofcource i cut all ties with that girl and the workplace. I have been trying after that to repair things. But after two years now she still brings these up, like the way that is toxic. Arguments have been going physical. She tells me to leave but doesnt let me. Holds the door and takes my stuff. Also these arguments happened before cheating. She take my personal belongings like even clothes, phone, passport, wallet and so on. Then she hides them around the house and only gives them back when i beg her for forgivness. She never had sayed sorry to me, never. Only i have to make peace. She throws water on me and twist my fingers. Cracked my phone screen while trying to take it away.

I have been so many nights outside or in the stairwell or in the car because i dont want that my kid sees this.

There so much more but i cant write it all.
