I need some outsiders view. Whats your perspective?

My ex/ baby daddy says things like..." I love you, I miss you, you're beautiful, do you want to be with me?, I don't want any other woman but you, i won't hurt you, it won't be like last time." I want to believe him but I have my doubts because I don't trust him. He cheated me last time we were together. He was mean and at the time I didn't know he was an addict. So fast forward 6 years. he's saying all the things to me. I told him before im uncertainof my feelings. I've been single for 6 years. He was my last relationship. So over the weekend my son and i went out to visit him. We were eating and his fb messenger rings he silents it. It rings again. He answers it and walks outside with it. I heard a girl on the phone and he was laughing and said ok I'll call you back later. He comes back in touches my hair. I shrug him off. Then he asks if we can talk. So he asked me what wrong. I said it doesn't matter. He said you're upset I can tell. I asked about the phone call. He said " she's a girl from the center. We're just friends. She's after all the guys there. I told her not call while my baby momma and son were visiting. She asked why can't I call while your baby momma is there? He said because it will cause a conflict. I told him wow she sounds respectful and classy. Why be friends with someone like that? He said I don't know but I'll talk to her when I get back. (He's in sober living) . Well then when we left he said he would let me know I got back home. I had a bad headache. He called me 3xs and texted me. Then the next morning called me and got mad because I didn't tell him I made it home. Then he got off the phone and I didn't hear from the rest the day. And this whole he's been distant like he's giving me a silent treatment. But I haven't been really talking either because I think he's lying to me. So because I'm all in my head and shutting down. He's not really talking either.
