Rusty, this is what I do for a living and have done at a very high level for nearly three decades. You do NOT want to fabricate a defense, even if you think you can prove it. The Court and the prosecutor will smell it a mile away as a concocted excuse for bad conduct. IMHO it is much more persuasive to be humble, apologetic, and have lots of people testify that this is out of character for you. Then you can make it clear that, although it is no excuse, you had a lot of atypical pressures converging on you simultaneously when this occurred, that those no longer exist, and that you have been a model citizen and father since the incident. THAT would be MY advice. I am not your lawyer, and you are NOT entitled to rely on this theoretical advice.
