Ok I couldnt sleep last night for worrying about it all. I phoned my cousin in OZ to find out how she was so certain about it all, long story short the b8stard and his bit of fluff told his best friend (a girl, and really good friend of mine and my cousin) everything, that they were in love and how long it had been going on for.
I then decided to talk to my best friends sister (we all may as well be sisters) I told her what I knew and said I was struggling with what to do as I knew how fragile my friend was. She was very upset too, we left it saying we'd speak today.
Just got off the phone with her there, shes adament we dont tell her. She said they had another row over the phone this morning, he's still not making any effort to get home. So basically shes inconsolable and her bp is through the roof again
Her sister rang the boyfriend in OZ and told him that she knew what had been going on and that amy deserves to know the truth but not until the babt arrives-he denied everything- a88hole!
So in short there is no way we will tell her while she is pregnant, shes in too bad a state right now. If he arrives home and baby is born and he still doesnt come clean I will obviously have to re evaluate
Thanks so much for all the advice guys, and sorry if the above story doesnt make sense its very jibbery!!! xx
