I need serious advice. No hate or negativity please

My husband cheated on me. We got into a huge fight and a lot of mean things were said on both ends and I ended up leaving a few weeks ago.

We’ve have a few more stupid arguments about that entire situation since I left. Most of everything was said out of anger and neither of us meant it.

Here’s the thing... we’re talking a break and I think today he might have had his realization that he’s not going to find anyone else like me. He’s been very apologetic and has actually given me an better answer that I can work with. And maybe not lose all my faith.

I said...if your heart is set on a divorce or separation we can do that. If you want space to think and figure it out or if you just want to start out as friends(still legally separated just not fully divorced) again and see what happens we can do that. Either way I’ve accepted the possibility of both situations. He told me he will have to figure how he wants to work this out before he can give me an actual answer but it’s not a complete “we’re finished”

We’d start counseling and take things very slow. Have ground rules and open communication . And start attempting to gain my trust back slowly. I know if we want this to work(and I do very badly) it’ll take quite a bit of time. So if anyone has been in this situation and has advice for me other than “he’s not going to change and he’ll do it again” I’d be appreciated. Because I do believe if he’s serious about this he’ll do what he needs.
