I get where you are coming from with you think what she is doing is wrong.
Problem is your W does not see what she is doing as wrong. She sees it as starting again and ridding herself of what she perceives is blocking her being happy(YOU and, possibly but I hope not, the kids).
This is her journey and you must, if you want to possibly R, let her complete this.
It takes mega patience and self control but if you want to do everything possible for your M then that is what is going to take.
When you start thinking about your W and OM just stop and go somewhere in your mind where you would be happy. A beach, maybe the woods, wherever you need to go to bring some happiness to your mind. If you don't this is going to eat you up man!
Also, it is quite possible that your W is not as happy as you are making it out to be. She is just filling a need that she feels you weren't.
Stop lying to your kids about what she is doing. Notice I didn't say tell them what she doing either.
This is tough for me because I have no kids hence, no experience with an issue like this.
If they want to ask their Mother questions it is there right but do not IMHO, push them to ask her questions that will be bad and will only be turned on you.
Maybe someone will be able to address this part better than me.
Most A do come to an end eventually. It takes 6-9 months for OP true colors to reasonate to the WAS.
If and when this happens, YOU need to be the stronger "new" man that only a fool would leave.
Work on yourself during this time to get to that point. You wont regret it either way I promise you.
Right now even though you are not confronting your wife about A or R or D. I suspect that your body language is conveying a very hurt and frustrated man. This is looked upon by your W as weakness. I understand why you feel that way. We all feel that way. We as LBH have to try our hardest to present a PMA. If we keep doing this eventually it will show in our body language and the image we project to our WAW and also others.
We are all behind you in whatever you decide to do just make sure it is well thought out and exactly what YOU want to do. Do not allow your emotions to get the best you.
Keep hanging on!!
