I’m currently pregnant high risk and have almost my lost baby at one point. Last night me and my boyfriend got into a argument and i called him out his name. He started driving crazy and he the roads are a mess, his sister who is a bigger women probably about 230 and me 120 was in the car and he kept saying “beat her ass” “when we get out the car start wailing on her” she told me “my face wasn’t pregnant and she would beat the shit outta me” i tried to go and he threw me on the stairs and she got him off of me and i left home. My heart is completely broke Bc i never would have thought he do me like this he’s always so sweet and kind to me. (He was drunk) and me and his sister i thought we’re close. 💔 I told them i was bleeding to just run out the house i pray i didn’t jinx anything. I tried to call the police and they kept calling me “scary little bitches” now he’s texting me trying to be sorry but idc wat if she would have jumped on me. “Yo face not pregnant hoe” is all i keep hearing. His mom was on the phone to and yet to have checked on me as well. I just see we all not as close i thought we were these last 3 yrs
