I showed my greatest sincerity in the next sentence

So it’s not me who should be sorry. "I showed my utmost sincerity" means that I have given everything I can, "so I am not the one who should regret" means that under the premise of giving everything, I have tried my best and faced the situation that has already happened. Some results have nothing to regret.
