I need opinions. Something!

my situation is confusing, please no bashing. And sorry for being all over the place  

I met my DH when I was 17, he was 16. We’ve been together 11 years now. He already had a child that the BMs mom took custody of because neither the BM or BD were capable of taking proper care of her.  She was born when he was 14. (Yes I know, super young).
