Need a Plan for My Marriage

[LSG]

I am still hoping to receive the information on the OMW's contact info. tomorrow. I am not sure how to open the conversation. Since we only have one car, I will be calling her. What is a good way to approach her? I would appeciate any input from others that have done this. What was it like for you to this? I imagine it is awful to tell someone their spouse is cheating. I am a little stressed about this phone call.

Thanks.
