Anyway / Well / Oh well
Used to wrap up a topic, express resignation, or move the conversation on. Often signals that the speaker has accepted something they can't change.
Anyway, what's done is done.
It didn't go as expected, but oh well...
—How did it go? —Oh well, better not to talk about it.
Anyway, we'll see what happens.
Well, I don't want to talk about that anymore.
