Hi I've just found out that the father of my son has got engaged to somebody else and they have a child on the way. I'm struggling to come to terms with this as my ex has not provided for my son by then he brings another baby into this world. My ex is saying that his new fiancée is my son's step mummy even though my son hasn't seen his dad since he was 15 months he's now 3 years old.
What am I meant to be feeling about this and should I tell my son that his daddy is in a new relationship with a half brother or half sister on the way.
I'm so confused as what to do. Any advice would be appreciated.
