This is a bit of a back story, but I have 2 ds (6 and 3) and I am pregnant due next month. My older DSs dad doesn't see them, so I was really pleased when I met my current fiancé but he's already got a child with his ex who causes lots of problems for us. She always comments on my scan photos on Facebook, she has photos of my ex up. She clearly can't move on. AIBU to think she needs to back off?
