Trigger Warning- Death

Back story- my daughter has never met her biological father, she is about to turn 13. When she was 3 we moved to a different state, we sent 7 certified letters to give him the chance to respond and keep us in the same state. No response at all. He only had her on his insurance and her last name is hyphenated with my maiden name and his last name. And always told his ex wife and whoever else that my daughter wasn’t his.

My parents always said it wasn’t a good idea for my now husband (married 7 years) to adopt my daughter because her biological dad will get her for the summer and etc. and they didn’t think her biological dad would sign his rights away. They didn’t want her to go stay with someone whose she’s never met and so on. She has a half sister who they don’t know about each other.

I would love my daughter to be adopted by my husband and for her to have our last name.

Fast forward to yesterday morning- biological dad’s ex wife messaged me on Facebook saying he committed suicide.

My parents don’t want me to tell my daughter because she started attempting/ having suicidal thoughts that started end of 2019 to present day. She’s been doing much better but I feel like I’m hiding it from her but I also don’t want to make things worse for her.

Should I wait or tell her?
