Am I moving on too quick?

Question*****Myself(38M) So I've def had a rough go for the last 7 months. My wife(33F) moved out then and immediately started dating someone else saying lost feelings for me. I said fine fuck that. And started the process of moving on, I cried, I bargained and i hurt. We still talk cause have still haven't finalized everything fully for the divorce. But keep it to minimal contact. But I find myself less bitter, sad and angry. To the point of feeling like I don't even think about her at all alot of the time. Despite her creating a massive blow to my ego with what she did. I've started dating again and find myself in a much better place. But we were together for almost 12 years. And I find myself moving on easier than I did in even some of the relationships I had in my 20s. Has anyone experienced this, this soon? Am I truly moving on or is this just a false feeling and it will hit me again soon and I'll fall back? I mean I still have anger at her for destroying what we had. But it's more of a feeling of regret then remorse. Should I be concerned I'm moving on too quick, cause I'll be honest I feel like I have moved on too quick?
