I will try and keep this brief and am looking for opinions from both parents and step parents.
I had DD from previous relationship, she never met her father and when she was 2 I married my DH. DD always knew DH wasn't her biological father and has never called him dad. DD is 14 now and we have a DS6 together. My DH and DD have had their differences however he has provided and parented DD for 12yrs. Recently DD wanted to know about bio dad, I facilitated contact and they met for the first time. I stayed with them and it all went well, nerves on all sides but was a success I would say and bio dad seems keen to maintain relationship.
Here is my problem - my DH (understandably) is feeling a bit pushed out by it all, he is being supportive and DD knows non of this but l can see he is struggling. Firstly with me now having contact with an ex, which I just want to point out I didn't care too much for when I was with him 14yrs ago and have zero feelings towards him anyway, it was more a fling. And secondly, because he feels as though DD is essentially going to go off into the sunset with new father and he will be forgotten about after having raised her for 12yrs.
I expect all adults to put their own feelings to one side for the sake of what DD wants and would like there to be a friendly relationship with ex for her sake, DH isn't so sure.
Any advice on how to navigate this would be appreciated.
