Me and my partner are about to break the news to my children (18,6) and his two from previous relationship (19,18), his two children haven’t been too keen on our relationship from the beginning. However we do want them all to know at th same time. My partner is going to discuss this with his children, but just looking for any advice on someone who has been in this situation or can advise on different options to try and make this process as simple and at ease for everyone as possible. We feel they may erupt in anger . Any advice would be appreciated. Thank you
