good at snatching misery from the jaws of happiness,shame as I quite like her

Exactly. As I said up thread, deny everything and demand proof. They all know what a b* Tracy is. Easy enough I would have thought to shoot her down in flames.....

The Old Carla probably would have fought back and schemed to get her own back on Tracy

The Old Carla wouldn't have done a lot that she's done in the last year or so, they've completely ruined a once great character.

The writers are Carla's worst enemy.

The old Carla would have wiped the floor with Tracey. I would have rather she had been killed off than made to look like the writers have made her look this last year.

Her confession made no sense whatsoever. Who on earth would sabotage their own wedding ceremony in such a fashion? Telling her bridegroom she was having last minute doubts might just be plausible but confessing to a one night stand in the middle of the ceremony? That's completely off the wall and bears no relation to real life.
