I need motivation!!

Hello guys, i need some type of motivation or encouraging words. Whatever it is. Any advice is appreciated. So, i am 24 years old, i have a 4 year old daughter and have been with her father for about 5 years. Ever since we had our daughter, our relationship problems have been non-stop. At first, i would forgive him after the disrespect, i feel like i was the only really trying to make things work for our daughter. But i’ve come into realization that i prefer for my daughter to have a HAPPY single mom, than a married mom who is always sad and stressed. I work full time and pretty much take care of all my personal bills. He has always pay rent, but i make enough $ to move out and get my own place. I just need the motivation to get out.. i really have to. i’m so miserable in this place. But i don’t know where to get started. Do i talk to him first? i know he would go crazy. Do i just move out? How do i tell him that he will need to support me with some $$ for our daughter? i’m so scared of the idea of just being me and her.. what if i struggle financially. Please i just need help.
