Need advice

So I confessed to cheating on my fiancé over two months ago just a one time thing. Yes I done wrong and I’ve been facing my consequences to this day. But before I cheated I felt like our relationship wasn’t the best nor the worst. It hardly wanted to make time to do anything with me or our kids unless I planned it months ahead or bitched about it. I know it’s gonna take time to fully forgive me for what I’ve done and if he will ever fully forgive me. But we’re trying to work on things which I’m very thankful but I don’t wanna get back to where we was and he barely have anything to do with us. What do I do? I’m not blaming how our relationship was on why I cheated but it was a small part of it.

Update when I try bringing up anything he thinks I’m trying to blame the whole cheating thing on us not getting to spend time together and flips out or shuts down
