My Fiance Died 😭😭😭

I don't know how this happened... One minute we are watching a movie, the next my fiance is having a heart attack... I watched the ambulance take him away. When I got there I hear from a doctor he died in the ambulance... They don't know why. Just that he had a heart attack... My 11 year old always saw him as a father.... Her real dad raped her and my fiance took her with open arms and love her. He was HER dad! I had to tell her that her daddy died. Watching my daughter fall to the ground crying was awful. Watching her say she wanted to die to be with him killed me... I want to kill myself too.. but my baby needs me. We were gonna be married in two fucking weeks. And to make everything worse my period is two days late. I was gonna test after a week but now I don't even want to know... I just want to crawl under my bed and die forever....
