Fiancé wants me back

Hey ladies! So I want to make this as short as possible. My fiancé has lied on multiple occasions about women, I’ve discovered everything from texts to photos to him being elsewhere when he’s supposed to be working... the whole 9. I told him I was done but unfortunately I am already 20 weeks pregnant and we live together.

He’s now trying to get me back but I don’t feel I need to be with him anymore. I’ve thought about it and he says he’s going to stop and he wants to go to couples counseling. The thing is I can’t deny I love him dearly, but this time if he’s serious about me and this family then I want proof.

Would I be overstepping some kind of boundary if I required him to reach out to all of these women (especially his child’s mother who he disappears for weekends to go and see and tells each other that they love and miss eachother🙄) and let them know he is no longer available. I want to hear the phone calls and everything because In the past I just went with his word that “he’s changed.” Would it even be worth telling him that’s what I need to even consider moving forward with him?

It’s hard because we live together and he literally pays all the bills because I’m not working due to this pregnancy. He also travels a lot for work and I don’t know how I’m supposed to really trust him again when in the past his “work trips” have been ways to disappear with her and stuff...
