My fiancés ex is pregnant again after having 5 kids taken 1 in which we have full custody of an she has no interaction with for the past 2 years , well ran into her aunt today an first thing to be told was aye your dummy of a bm is having another child , why is it they keep letting her have kids if they keep taking the children , why havent they tied her tubes after the last baby , she’s basically a baby factory its so sad for these children my stepson doesnt even know his brothers an sisters because the whole family just talks shit or bad influence on him when hes old enough to understand an make his own choices we will let him decide for himself , i mean hes done a drastic turn around since weve gotten him an I wouldn’t change it. Just wish they would all just leave us alone an no we dont care about her life ( meanwhile they know weve been trying for years anthats the first thing they tell us when they see us about someone who isn’t deserving of a baby)
