You weren't alpha enough. When she first said no is when you seduce her and make her cheat on her then boyfriend, perhaps making use of your old friends alcohol and roofies. Then you degrade her into thinking she can do no better than you because she is a cheating whore. Once you have her in, you slowly unravel her life, banning her from seeing friends and family. If she backtalks, you beat her with bags of oranges so you don't leave marks - but always apologize profusely after. Or, you could just move on.
