Breeding behaviour

So i am new to breeding hognose and im looking for as much advice and information as possible on breeding hognose snake iv kept these animals for a long time as a hobbyists and i care for many reptiles at work so im no beginner to looking after them but breeding is my next challenge iv introduced a good weight male (never mated before) to a good size female (proven breeder) i saw good things a good response from the female but never saw a lock, they was together for a few days, i separated them to feed for a few days my male has rejected food since been in with her, she is smashing food, i tried to put him bad and she instantly rejected him puffing and been agressive this is as far as i have been with these animals, thanks for reading and advise would be awsome or if the lack of feeding and female aggression is normal.

Many thanks guys
