Hi, I found this post and was amazed how similar your situation is to my own. And how quickly I found it when I found out my husband cheated on me a few days ago. If anything that should be a testament to me of how God works...but I haven't been feeling very religious since i found out. Never the less, I thought I would add to this post in case you wanted to talk to someone in the same boat.
My story is about the same as yours except I had our baby a few months prior to finding out, and we have been dealing with the porn addiction for over a year now.
we haven't talked with anyone yet even the bishop b/c we are in a new ward, but he agreed to try counseling.
I'm kind of going nuts because I don't want to tell anyone about it and at the same time really want to talk about it.
I would really like to hear how things turned out/are going. thanks
