My friend has been dating her BF for over a year, they live together and it was all going well. She found out yesterday that he is married with two children aged 1! and 5. She is upset about this but doesn't want to leave him and therefore tell his wife so that she hopefully leaves him etc.
I am in a very stable relationship at the moment, I am getting married soon and therefore can't feel what she is going through (her words, not mine.). How can I help her as a good friend and what's the best advice to give her?
