New kitten introduction

Hello guys,

I once posted my problem here and everybody was so helpful so here I am with a new problem.

I have a neutered 1 year old Ragdoll - male and on Saturday a 14 weeks old neutered Ragdoll female kitten was brought here.

I watched all the Jackson Galaxy and other videos about a proper introduction, read forums etc and felt like I am ready.

On Saturday the breeder brought the new kitten and I told her that I want to introduce them slowly. She said I am exaggerating and that my method is not necessary. Befofe I could express my concerns, she just let the new kitten out and let her meet my 1 year old male cat.........

At first there was a lot of hissing and then the breeder and her friend left after 2 hours and things got a bit better. The 1 year old doesn't hiss as the kitten anymore and is very curious about her. Their noses have touched 3 times since Saturday. I give them food in a way so they face each other and separate them at night. I sleep with the new kitten. I also separate them during the day whenever the 1 year old starts getting mean to her. I feel like he is hunting her. He hits her with paw and bites her. Sometimes she really cries and I never know if I should shoo him or not. I don't want her to get hurt but also don't want them to get interrupted.
He ignores all toys in her presence and watches only her. I pet him a lot so he doesn't feel like he is getting less love because of the kitten. He doesn't cuddle with me as much, only headbutts a bit.

Yesterday she was sleeping on the cat tree and he climbed up there, lied next to her and fell asleep too. I thought this is it, they are friends! But after they woke up he would hit her / bite her again.

Should I keep interrupting these fights or? He doesn't hiss at her but she hisses at him if he starts being mean. I can sense she is a bit afraid of him.

I will appreciate any tip!

Thank you very much and I apologize for the long post..

The breeder of my newer cat insisted that putting cats together and just letting them fight it out was the best way, she kept warning us that introductions go worse when they are separated for days. I ignored her, breeders are like anyone else they have their ways of doing things which may not be the best for the cats.

We had feliway on for weeks when we were introducing ours. And I felt no qualms at all about separating them when things started to get rough. Whenever we separated them they were immediately sniffing and putting paws through the door at each other.

The fact that your cat felt comfortable enough to sleep in your other cat's presence is great, you will have hiccoughs at the beginning which will lessen over time, it's ten months later for ours, it often felt like one step forward, two steps back but my cats do enjoy each other's company these days. 

So would you let them be now or should I separate them?
I really don't know. He pinned her down today and she started crying. Over the night I had them separated again. I just don't want her to get hurt and associate this place or my other cat with fear..
