I have a 1yo. My ex took her under his wing and has actively been parenting her with me since she was born. As far as he's concerned she's his and he is the person she has bonded to and sees as her dad.
We split up a few weeks ago, but he is still actively parenting her, actively involved in her life, and will stay there.
Is it inappropriate for me to get him a card from her for Father's Day? Her bio walked out and exSO has been there since.
