A few people have used the phrase 'move on' but I think it's more helpful to say 'process this'. You quite rightly experienced a trauma through this man being unfaithful and deceitful....for two years! That's awful. He is awful.
I think maybe you are carrying a burden of shame over what happened and you are trying to deflect that deep sense of unrecognised shame by objectifying the other woman as the homewrecker. But actually, perhaps your shadow side believes you are the homewrecker, for making him leave. That's a very hard place to be in and that must really hurt. No wonder you're angry. I would be too.
They say that 'criticism is actually an unmet need' and anger is a sign of a boundary crossed. What needs do YOU have that have not been met? What boundary within your code of honour was crossed?
Give yourself the right to process all of this with a really good counsellor. Thousands of people have been in your situation. It can manifest as an identity crisis, complex PTSD, abandonment anger, a whole range of feelings and ALL OF THEM are valid and real.
Anger is actually love, it's anger at what's been lost. The opposite of love is indifference, the feeling of no longer caring. That's the place you need to reach and you deserve to reach it. You are a remarkable person just as you are. Don't let a sense of shame cloud you or harm you.
You absolutely deserve peace.
From my heart, I wish you the very best of luck should you be a brave lady who goes on that journey back to YOU and all the good things you know you are.
