Hi Coach. Very sorry you find yourself here but you have come to the right place. Welcome to SI.
First, you are going to get hit with a lot of abbreviations and you can find most of the abbreviations here in the upper left corner in the Healing Library. Please check that section out.

I would be extremely cautious about just kissing. Almost all waywards trickle truth (TT) you and the real truth slowly comes out over time. I'm sorry but my personal opinion is that she was way too comfortable doing that with kids around. IMO, they are past kissing and you did not get the truth. Gently here, you both need to be tested for STDs. Ask her to get tested to STDs and pay close attention to her reaction.
Your WW is NOT remorseful. She regrets getting caught. Most remorse doesn't kick in until the fog wears off.
Also, did you tell your neighbor's wife? She needs to know immediately for several reasons. First and foremost she needs to know. Second, having a second set of eyes will help prevent the A from going underground.
All those texts messages, have yo useen them? If they were deleted there are different software packages that can restore them. But the one that fits your wife's phone (you can google them), then once you have it let your WW know that you are going to restore the deleted texts. See what her reaction is. Many times this is where the rest of the truth comes out.
I'm sorry Coach. Your WW messing around like this with kids nearby is is a special kind of shitty.
Please read those other threads. Keep reading. Keep posting. We are here for you.
