Hi Tammy,
First of all, I just want to say I am so sorry you are here, but glad you found this great place! I've gotten so much support and advice here -- better than I've gotten from either of the 2 MC's we went to!
The effect on kids is a real hot button for me, so I feel the need to chime in. I'll share a bit of my story -- sorry I know this will be long.
My DS (then 14) discovered the A by seeing a text on his dad's phone during a family vacation in July of 2012. He told my DD (then 16) and they cried and commiserated, but decided not to tell me. They didn't want to break up the family.
My DD ended up confronting my WH in September, but only told that SHE knew. My WH asked her what she wanted him to do - she was 16!!!! She didn't know how to answer. So Mr. Wonderful decided to keep his A going and let her deal with all her internal conflict. (yes, smoke still comes out of my ears over this!)
Fast forward to my DDay, Feb of 2013 when my WH said he was moving out. I asked if there was an OW, he said yes (knew he couldn't lie, as the truth was about to hit the fan). After we told the kids he was moving out, my middle DS told his dad he also knew about the A. That's when reality finally blew a small hole in WH's fantasy bubble.
My youngest DS was 11 at the time. He was so shocked by the separation and very clingy to his dad. We all agreed he didn't need to know the "truth" because it would only hurt more.
We struggled through R (maybe false R) for the summer and things took a bad turn in the fall. I found SI in August and through the advice of many here and also my MC, I decided I needed to be honest and authentic with my youngest DS in an age-appropriate way. It was horrible. But it was the right thing to do. We talked about it A LOT and I held him while he cried.
I continued to have conversations with each of my kids. No gross details, but I listened and also shared with them some of what I had learned about the "science" of A's and their addictive nature, etc. We talked about choices and truthfulness and all that. I think it's VERY important to be honest. We think it will hurt them worse, but as a BS, we see how much the lies and deception can be even more damaging than the A itself. I believe the same is true for our kids.
I wanted my kids to know that I will never lie to them. That they can count on me, no matter what. I don't do this out of disrespect for my H. He already chose to lie to them. That's his hole to dig out of. I want to be a rock for my kids. I want them to understand my reasoning for trying to R -- that I'm not a doormat... I want them to respect me.
I will tell you that my DS (now 13) had a meltdown in May of this year (and I thought we were all doing pretty well) and expressed his anger that he was "kept in the dark" for those 8 months while his siblings knew. I tried to explain that I didn't want to hurt him further and that I was in such pain myself, I wasn't ready to try to help him heal. But that I eventually decided that I had to be honest in all aspects of all my relationships and finally told him. That I didn't lie to him to hurt him, but I eventually understood that the lies would hurt worse.
Kids know WAY more than we think. I am CONVINCED of this. We do not protect them by hiding the truth. They are left to form their own opinions (everyone lies, everyone cheats, etc.) This is part of my WH's FOO issues. This way of thinking perpetuates the cycle. Our kids will repeat what they see. If kids are REALLY young, I can see not telling them. But teens and pre-teens are well aware of relationship dynamics and are seeing A's on TV all the time.
Sorry this was long, but I felt I needed to give context to my views on this.
I have a good friend who was a BC and advocates strongly for talking openly with your kids about the situation. Sharing your own thoughts, feelings, insights, hurts, and letting them share their own. I've seen my own kids "trigger" and didn't even understand how they are riding their own emotional rollercoaster. Our kids need our support. They need to talk through this to form some understanding. If you are trying to R, they need to know that you are in it if your WH is willing to do the work and change. That you have expectations and will not accept any more infidelity. This gives them a basis for how to handle their own relationships in the future. We need to lead by example.
I desperately wish I did not have to have these conversations with my kids and that this horror would have never have entered their lives. But we can't put the genie back in the bottle. It did happen and they ARE affected. The best thing we can do is to help them through it with honesty and compassion and lots of love.
I wish you the best. I wish peace and healing for you and your kids.
