Need help.. advice

Hello girls 👋🏼 As a younger woman. I need advice from all you ladies here... As i am having a hard time knowing what to do and what decisions to make. Sorry about my long post. Hopefully, some of you read through it. I am 25 years old, have a 5 yr old daughter. I got together with my daughter's father back in 2018. 2 years later, we had our daughter. For some reason, after our daughter was born our relationship became very toxic and problematic from both sides. It was full of verbal abuse and at some point physical abuse. I was stuck in that situation for 3 years. One day, on January 2024, i decided to grab all my things without telling him a single word and moved out. Mind you. I've always worked full time and paid all my bills, so whenever i moved out i was not worried about not being able to provide for myself and ny daughter. Thankfully, i was able to manage on my own. Throughout the whole time him and i kept in contact for our daughter. For some reason he left the apartment that we had together and decided to move in with a friend. Fast forward to January 2025. A whole year after moving out, he told me that he wanted to work things out and that he was working on himself. I gave it a shot and told him that if it was meant to be, it would be. So from January-April we were working things out and we were doing much better. I was still living on my own and he was still living with his friend. Around Mid April, apparently him and his friend got into an argument and his friend kicked him out. After he told me what had happened (mind you. I have a humongous heart) he told me he didn't have anywhere to go. I told him that he could come stay with me while he figured things out. Exactly that same week my landlond had a 2 bedroom unit available. Which i was looking forward to, because that was my plan. To get my daughter her own bedroom. So, i told him that it would be a great idea to get the apartment and move to a bigger place. My mother told me to get it and that if things didn't work out with him. Just told tell him to help me financially with our daughter. So we got the apartment. The first few days things were good.. i dont know why, but now things are just going back to how they were when we lived together the first time. Verbal abuse... him calling me bad words. Being controlling. These past days i've felt so miserable because it took me such a long time to get out the first time 😭 and when i did. I was living in so much peace and happiness just worried about my self and my daughter and i feel like i have failed because i went back to the same situation. I've been asking him to leave i the nicest way possible and all he tells me is that he doesn't have a place to go and won't leave.. im literally so stressed about this situation. I feel so stressed that im having a non-stop headache all the time. I don't know how to make him leave... but he has to go... he really has to. He's messing with my mental health. what can i do?
