Need help

Hello everyone I am in a situation and I would like some advice. I’m in a toxic relationship and it seems to be getting worse. I know what i need to do Im just not sure how to go about it. I want to leave and lose contact with this person but no matter what I do they reach out to me and I end up taking with them again over the false hope I give myself. What I would like to do is just be here and be silent and then just leave. I have very little money and if not I wold just stay with my mom and save but I don’t want her in the mix just in case things go bad. Can you guys give some advice?
