I am so, so sorry. No one should have to go through this. When your husband told you, did he make it sound like it was a one-time thing or a real affair? Both are heart-breaking, but if it was a one-time affair and he is REALLY sorry and completely transparent about all his future interactions and works like crazy to rebuild trust and you love each other, you will have a foundation to rebuild your marriage.

The children make this hard to just walk away. If there is remorse, he agrees to seek out help (marriage counseling or personal therapy) and you have the foundation of love, it is worth rebuilding.

I have been dealing with something like this with my wife cheating via cyber sex and phone sex but we both still love each other and have reforged a new bond. I think the bond will last.
