oh yes. a nasty one for me. too long of a story but i'll cut it short:
My so called best friend who was 8 months pregnant to her hubby - and my hubby at the time decide to get together and have a fling/affair.. nice. After 10 months he decides she isn't the one for him and wants me back. Over my dead body mate. Found out 5 months later my whole group of girlfriends knew about it and said nothing... also after putting up with his abuse it was the icing on the cake. I had a massive breakdown, it was horrendous and it totally changed me 100%.
I have got walls up to the moon I reckon. And this was 13 years ago.
