Is it weird to raise a children with another woman ?

So my best friend and I are raising soon two be two kids together . He ex was a wife beater and I've not had the best guys either . We are both straight  (truely there is not he sexual about this ) both children are hers but I've been there since before  birth for both . I am both children's Godmother if anything happens to her they will both come to me . We both do everything for them and we are both mommy . Lots of people give us looks and I don't think it's weird but wonder if others do
