So my fiance's ex wife, who he has 2 children with is now running her mouth and having their 5 year old son tell everyone that my daughter isnt really his sister because they're only half siblings. Wtf?! All my siblings are half siblings but I've never referred to them as such. They're my brother and sisters. God shes so irritating. Honestly, would anyone else tolerate this? Or have any of you gone through this? If so, what did you do about it?
