Dh has a child from a previous relationship, I’ve always known about this and they split not long before we met. This is a complicated situation and I’m seeking some advice, please be kind. Dh claims that he was used by her to have a child, that he was nothing more than a sperm donor. He claims that she is poison and “mentally unstable”. He also claims that she would destroy our lives if he was to have contact with her again. Early on in our relationship he tried to meet his child but he claims that she stopped all contact and sent him abusive messages. His name is not on the birth certificate. He has continued to pay child support for years although he’s never met his child. Dh suffers from severe depression and possible bi polar disorder. His child has become the elephant in the room in our relationship and he completely shuts down if I try and discuss it and what he is going to do. We have children of our own that have no idea that they have a possible half sibling out there. He recently received a letter from the child support agency, just a standard letter about payments and he’s been traumatised ever since, he isn’t sleeping or eating. He says that the whole situation has left him completely traumatised. I have suggested that he try and meet his child but he refuses to even discuss that. Seeking some advice please.
