I agree with you Tomi.
I think your neighbor should have told you too. She was protecting herself, in my opinion and she definitely wasn't being your friend.

I think relationships need trust and you can't trust your partner if they lie to you repeatedly. I believe people can grow and flourish in their relationship if they tell each other the truth, even if they have had an affair. Bringing it out in the open and working through it is hard, but it can be done. Many of us choose not to do this work and find someone else. That's a good option too.

Anyway, this is what I think......today. : I wrote a post on my blog about this but haven't had any comments there yet. Hope no one bites my head off for my beliefs!!!
