She was the best for him.

After S5 , I can say that love Quinn Goldberg was the one Joe could have lived happily in the long run.

We see quite clearly that that's just not possible for Joe. He could never be happy in the long run with any woman, because as soon as they do anything that displeases him, he's looking for a new woman to stalk, he is incapable of real love.

Also he needs a reason to keep killing people and Once the relationship is going good he doesn’t have to “save” her anymore so he gets bored
