Rejected Once? And Now I Have A New Mate?

I was always told once you find your mate, everything was up hill from then on. Did anyone ever-EVER- think that a mate could be selfish, cruel, and heartless towards their other half? Could anyone have prepared a young girl to be heartbroken? To have her mate, who she was supposed to love, cherish, grow old with, think her older sister was prettier? Just because she was 16, had breasts, and more experienced? Even though her sister was a dormant wolf.
This is how I was chosen second behind my sister, again.
How my own Alpha’s son couldn’t even accept me as his mate.
How he couldn’t even think about his own mate’s feelings, or how it might hurt her.
How he used his very little Alpha command on his own mate to keep her quiet.
How he told me I was never going to be good enough for him.
This is how my own mate gave me heartache, try to kill me, banish me… and how this all led to love.
