Should we tell our exs πŸ‘£πŸ‘£πŸ™Š

kay β€’ Can`t wait for my wonderful family to grow
Been married 3 years and my husband and I are having our first baby together. He has a Lil girl with his ex and we have her sometimes when the exs allows us. So we decided to tell the family this weekend as I'm 10 weeks and his Lil girl told her mum who hates me she has been a hell to deal with and has tried everything to break as up. I feel like I don't want her to know yet but she's been ringing his whole family asking them if we are having a baby. She attacked last year and I feel she may do something to me if we tell her. What do you guys think we should do. I'm so confused πŸ˜•
