[It wasn't confidence, it was denial. Denial that the person he thought was one of his closest friends could be someone completely different. And the accusations came from the one person Anakin trusted the most. The Force gave away no indication of deceit or lying (not that Oni-Wan was known for such a thing anyway).

He felt so very conflicted, not only because he heard Obi-Wan's words despite his open denial but because the pieces suddenly started falling into place.

Little things said here and there. Comments Anakin usually dismissed as nothing important. But then there was also story he told. One Anakin questioned as being a fable but also was unable to verify. ]

[He took a very small pause before continuing]

[Which is not to say he didn't try to get in there ]
