Step daughter/ custody / support.

Me and my husband had custody of my stepdaughter since she was 2 years old.

My husband passes away when she was 6.

I still had custody since the mother was a piece of work and then adopted her when she was 8 legally.

My daughter ( step, adopted ) is now 10 the mother contacted me about visitation and honestly, I wanna say, go fuck yourself but.... I'm not sure, she was a heroin addict, who tried to sale my daughter ( her biological) when she was 1 that's how we got custody in the first place. I fought her In court after my husband passed away and git granted permission to adopt.

What would you do? Legal I have no obligation, supposedly she fixed herself up, got clean... but I dont trust her.

FYI, MY DAUGHTER DOESN'T WANT ANY CONTACT WITH HER WHAT SO EVER**

But, I don't want her to not know her, but I dont want to force her either.
