Sending some other girls sexts?? Cheating🤔

Hey ladies. So I’ll try to make this short and sweet. I was dating this guy for around 10 months when we broke up. I got suspicious and looked at his phone and found a selfie of a girl that he had been “joking around with” on her status about helping her pick out bikinis. I believed him. When we broke up it was mainly because he wasn’t treating me well, and I told him to get some help. Well he did and I welcomed him back into my life and he seems so different and it’s been so great. But then he’s getting these texts from this girl who he says just wants advice from him for a job that she wants that he has experience in...but they talk about other things too. Anyway. I got suspicious again, and he said it’s not anything that he wouldn’t do anything to lose me again. Well last night I checked his phone. Those texts from her are deleted (unusual for him) and I found this as well (edited so you can’t see her face) he sent it to a number in his phone that isn’t saved. Since talking this was the first night I was staying overnight with a friend of mine at a water park (ended up coming home at like 12am and he met me there) but the time on the text is 8:27 and he was talking to me at the same time!!! And obviously that’s not me. Ladies, what do you think? I haven’t confronted him yet. He’s also been talking to his baby mama who he supposedly hates (like small talk and even compliments) and has pictures that may be porn or selfies of girls.

Edit: he was hanging out with his guy friends that night supposedly and I think he texted this to a guy friend
