She probably beat his butt at one point in time or another.
Mine fight alot well one pair does but they refuse to seperate, they go on hunger strikes when I punish them. Ive seen them repair several times.
She is testing him and the more he moves away the more adgitated he is getting with her, he will at one point if he is capable stand up to her with a large display of force, then and only then will they truly be paired or not. I never segregate until they are truly paired and have spawned atleast twice.
