I don't feel excited for my pregnancy? 😭

What is wrong with me? I see everyone else post on here how overwhelmed they are and how over the moon they are to be pregnant and then there's me. I am not happy or excited one bit. I'm 12 weeks, had my first proper scan today and I felt nothing. My mum was more excited than I was! I feel such a terrible person. The so called 'father' of my baby has turned into an evil manipulated man! He's been so horrible to me over the last few months. Harassing me, stalking me, sending threats to me and slandering my family and making up dirty little lies about me. He is poisen!!! Don't get my wrong I want the baby, I just don't want him anywhere near me. Social services have been informed and they are now getting involved! He's ruining my life! Could this possibly be why I don't feel excited or happy? Because I'm carrying HIS baby!? I'm posting anonymously because of judgemental people on here!
