My Mate and Brother's Betrayal

Finding your mate is said to be the happiest moment of your life and for me it was. The man I grew up with and loved since I was a teenager turned out to be my mate. The next Alpha of the Black Rose Pack. What I didn't know is that he was torn between two loves. His heart did not just belong to me. When I replace him in the throes of passion with his first love my heart shatters into a thousand pieces. His pleas for me to accept him despite the pain he caused me hurts more than seeing him sharing a bed with someone who was meant to protect me. How can I forgive him? How can I accept our bond and move forward with our lives knowing his heart doesn't completely belong to me. My life won't ever be the same.
