I didn't know the man I was dating was married. He's in the military and I told his wife everything out of guilt. I'm sure she screenshot it and she told me I might have to testify. I'm only 18 and I don't want to go to court and testify. Can they make me? What happens if I don't show up or I'm in another state? Is the confession all she needs?
Military members can be charged for committing adultery under the Uniform Code of Military Justice.
He or she won't be charged with "adultery" per se, rather if charged it'll be under Article 134, which is known as the "General Article."
Article 134 prohibits conduct which brings discredit upon the military, or conduct which is prejudicial to good order, discipline, and morale.
Regardles of the specific charge(s), CONFUSED, you did nothing illegal or wrong.
You didn't know, but when you learned of his actions, you told his spouse.
You can be ordered to court and required to testify.
That said, only you know what you know.
Others might suspect you know something, they don't know that you know something.
What you do is up to you.
I suggest you simply answer the questions TRUTHFULLY.
You'll never get in trouble for telling the truth.
So, I suggest you just reflect on things, debate them in your mind, then you decide what you will do if called upon to take an oath to tell the WHOLE truth.
You can lie, and no one can prove you've lied.
But, you'll know the truth, you'll know you lied.
Think of it this way, what if you were on trial.
Wouldn't you want EVERYONE to tell the truth?
I wish you well, CONFUSED, you deserve it.
