Do men come back after they wronged a girl?

I was dating a guy (31m) for 2 years and it turns out he has an ex fiance who he has a child with who came back into his life and he never told me about her. He tried to leave without telling me and then I found out accidentally without him ever telling me. So at that point instead of confronting him, I backed off and left. I know the situation was messy, and i didn’t want to get hurt. He kept saying he had to tell me something but never did. I went no contact for 3 weeks- and then he reached out and claimed we were tg and that we had to move forward, i just listened to him, but said nothing. I just want some opinions on what y'all think may happen…. When I'm prepared for what may come I do a lot better… when i'm not prepared I don’t know how to navigate. I don’t block people, i let them be. I want to observe. Do y'all think he will reach out or he got the hint to leave?
