I Was Never Picked Why Do You Want Me Now

All my life I was never picked I was the nerdy , poor kid in our pack. My biological father up and left my family and started a new one. My older brother and I are total opposite from one another player football and I was the dorky nerdy kid sister. One day after my birthday I was supposed to be running our pack runs since I was a wolf now I was in the food after my shift I was changing my clothes. I smelled something so sweet and mouthwatering 'mate' my wolf said I turn around and then I was push on the ground with someone kissing me . We were both naked and I felt him forcing his self on me and I look at his face it's the alpha of my pack." Hey wait what are you doing !? NO I DONT WANT THIS ! GET OFF !!!! I don't want this !!!" I yell and i start to scream as he forces me on the ground and starts to rape me. I continue to scream for help because it hurts so much I don't want this. " HEY GET OFF HER NOW !!!!" I look up and I see the betas, the omegas , the Alpha's father and Luna. I see the neighborhood pack alpha and his betas and their alpha mom and dad . They pull my mate off me and the lunas rush me off to the doctors since I have bruises all over me from
Him pinning me down. As I put on my clothes before I left he said ." Don't tell anyone we're mates. I will only sleep with you, I have a reputation to up hold !!!I could never be seen with you!?" He says as the boys pull him away and off of me. I feel my tears rushing down my face and the lunas rush me to the hospital to get checked up on. Since they witnessed what happened they offered me a deal I could stay here with him or I can move int to neighborhood pack.once I was released I went home and I packed .My brother sees the bruises and he holds me tightly." I should of been you. I am sorry." 3 months later I haven't made contact with my family or old pack but I ended up pregnant with his kids? How long will it take for them to realize it? Would I have to see him? Could I raise my babies on my own?
