He has just gone upstairs to phone her - I said I would not go upstairs until he came down. I can't cope with this it is killing me. Why is he doing this? I am trying to keep calm - I am not crying but on the inside I feel so sad. I need to do something to change all if this - it is all wrong! How can he do this to me & kids? What can I do to make him stop - should I just ask him to leave. ? But then what? Do I just pretend it's not happening? He is in our bedroom - probably sitting on our bed talking to her while I am downstairs!!!!!!
