It depends on the circumstances of the breakup. If one party did the other wrong, probably not. If it was mutually agreed upon, then perhaps, if both are mature adults, I can see it happening.
I can see it getting there after time. My MIL and late FIL had patched things up 20+ years after their divorce. They both came to family events with their respective new spouses and things were more than civil.
But it often takes time. If there was bad behavior, then a real apology is in order.
For example, my ex-wife thinks her affair and lying to me was justified because she wasn't happy. I'm willing to accept that she wasn't happy, and there were things I could have done better. But as long as she justifies her deceitful behavior with this, I don't see us becoming even civil. If she were to say she was unhappy, but how she chose to approach it was hurtful, destructive and she was wrong to lie to me by both keeping her unhappiness a secret by saying everything was fine, and then by lying about the affair, I could see things getting better.
But as long as she views it as all my fault, I don't see how anything can get better.
So it's how the folks view and handle their part in the breakup of the relationship. If they take responsibility for their actions and are genuinely remorseful for their bad behaviors, I think a peaceful new relationship can form. If they steadfastly hold to the view that it wasn't their fault, but all the other person, there is little hope for a positive relationship in the future.

I don't think so normally.
