Anyone know this werewolf romance novel?

I read it ages ago, it's about a girl who is being sort of forced to 'mate' with the alpha of the pack however her heart belongs to this other wolf that apparently wasn't good enough for her. I remember they get together in the end and the Alpha is heart broken but in the next book he finds his true 'mate'. I keep thinking their names were Belle and Aleks and Garth but it only links me to a Judy Mays book that i know isnt it.
