Is it bad that i'm staying with him knowing he has a kid on the way?

I found out in January that my boyfriend got someone else pregnant. Not only that, she was staying 4 blocks away from him And he was still picking her up. I had to drive to him (still do). I also just found out how old she is, where her mom lives and i found pictures/videos of her with my man having Raw sex in his phone from September 2022. (Which i deleted it). But yeah, their baby will be here in August. And i'm still with him knowing all of this. Even though, he says she doesn't know the dad is; I'm still bringing my daughter around him. I don't know what to think- i just don't want him leaving me alone for her and that baby. So far, he has blocked her from contacting him. I'm the only one who responds to her text messages because she needs to accept the fact he don't want her or the baby. She said it herself he hadn't been to not one appointment, never asked her was she hungry nor check on her. Last thing i read from her on his phone was she was homeless- which he still didn't reply to any of her text messages in a month. I feel like he loves me more than them now. I just know he does! just by not interacting with her. Is that bad that i'm staying with him knowing he's treating her like this while she's pregnant with his baby? I mean he told me not to worry but i don't know... It's sad she wants him as her kid daddy
