Am I the bad guy?

Hi In January I left an abusive relationship and the break up was really bad I have a two year old and work full time also helping my sick dad. My baby daddy reported me to police for abuse because I was trying to leave him, at this moment makes my life a living hell, and at this point very exhausted. My dad lived with me since I was with my baby daddy. Just recently my dad had started to get better and he offered to help me with my daughter so I can go to work. He would sit on the couch and play on his phone and never paid any attention to my daughter only if my daughter did something wrong. Today I was home from work, very tired trying to get the house work done such as cook, clean, take care of my daughter etc and our fire alarm goes off and my dad is on the couch talking on the phone and did not flitch to help me and kept talking on the phone. I called out to him to help me cause I was wet cleaning the bathroom and my daughter running around my dad hung up the phone and the fire alarm stopped on it’s on it’s own then when the person on the phone was not answering he became aggressive told me I was crazy, an idiot, a lunatic and mental when I reacted to him he just didn’t like how I reacted and came close to me and I told him to leave my home. He refused to leave got more aggressive said he regretted staying around when he left my mother. So I got scared and called the police. I’m I in the wrong for this? Or am I actually going mad? Or just so tired?
