How to move on…?

I need advice. Hopefully someone takes the time to read it. I am 22 years old. My baby’s father is 23. We have been together for almost 4 years. Ever since i got pregnant back in 2020. Our relationship started going downhill very very bad. He started disrespecting me on social media, saving pictures of naked girls, texting naked girls whenever they would post their “ass.” etc… It has been a relationship full of disrespect from his part. I have cried to this guy, i have begged this guy. Last incident was about 2 weeks ago. I noticed that on our camaras some activity had been deleted. I could hear that he was talking on the phone with a woman. I did ask him about it and all he said was that “ i am crazy.” I told him to just be honest with me and all he kept on doing was acting like the victim. He went to the restroom and i literally sat behind that door. and started crying to him. Telling him to stop acting that way. It has become a very tiring cycle. It feels like i just cannot do it anymore. I stopped loving him. I appreciate him as the father of my daughter, but that’s it. The only reason why i haven’t left is because of her.. Just the idea of having a kid together and leaving makes me feel super guilty, but i do not want to be in this situation anymore. I started talking to a new guy. I actually have been knowing him for years now. He had always admitted to liking me. He’s a very lovely person, but even talking to him makes me feel guilty. Obviously i would take everything slow, get to know him. But i do not want to make the same mistake anymore. He tells me to get out. That he’s willing to pay for an apartment for me. He accepts my daughter. On sunday i did accept to go out with him as friends. He told me to take my girl. And he was so lovely with her.. But like i said just the idea of leaving this shitty situation makes me feel bad. Please what can. i do? I’m young and i feel like im always crying, arguing, in a bad mood.
