I need someone to talk to about a problem and I dont know how to start

My husband told me he is having an affair and emotional one at this stage as he hasn't meet the person yet. It all started on facebook. After one of the children found some text messages on his phone. He asked the child to answer the phone and the text message prompted the child to look at other text messages.

They stormed off to their room and when I asked what was wrong. He calmly told me he was having an affair. An emotional one at this stage as he hasn't meet the person yet. It all started on facebook. Their is many factors in our relationship at the moment that are not reasons for what he has done but since finding out and discussions together over the last few days. He has now completely broken down and tomorrow is seeking counselling at his work as it has affected him their. Their is so much moe to say but I dont know if I should say it all or iI am allowed to go into details. I just need someone to talk to as this is tearing me apart.
