DS is five (ex boyfriend not his father). Last night I found out that my boyfriend of 6 months has been cheating on me throughout the relationship. I told him to get out obviously. I am so upset for my son as he has bonded with this horrible man and now he will never see him again, he will feel so hurt. How on earth am I supposed to explain this to him when he wakes up in a couple of hours? He has no contact with his father and this was the first father figure type person in his life, even though it was very early days. He will be distraught
