Welcome to the forum!
Sunnies are a law unto themselves, huh?
I can reassure you by saying that I went through exactly the same as you.
How old is Ra?
With the stick......do not worry if he is messing with it. Sounds like he is wary of it and the fact he is playing with it is a good thing. Let him. If you just hold it in the cage and make reassuring noises, he will soon learn it's nothing to worry about. If in a few days he is not changing his behaviour say gently but firmly "No, step up" and hold the rod just above his feet and press it gently towards him. It will all take time as it is trust as well as him learning about mutual respect.
With your problem of liking your bf more, we had that, but reversed. Cal preferred me to my husband.
Again, it just take time. If he is biting your neck and shoulders, do not put him in the position to. It is as simple as that. You need to work harder with him building trust.
The way we got round this was I had to tell my husband not to be so anxious for Cal to come to him. Everytime I successfully managed to get Cal to do a new thing like step up perfectly, I made sure my husband followed suit. Gradually she came to realise that both of us were the good guys

.
Our relationship stands like this. She loves me and does as I say pretty much all the time. We cuddle. She loves my husband and SOMETIMES does what he says. lol. They cuddle. Dave can pick Cal up with his hand around her body and put her on her back in his lap - this is their favourite game! I can blow raspberries on her and kiss her all down her back and she will lift her wings so I can kiss under there - this is our favourite game!
She loves us both equally, you can tell, but in totally different ways. She knows that her "Daddy" is a pushover

She knows that she must do as I ask and there's no point in arguing lol.
We have had her since she was 3 months old. She came from an aviary and was not used to human contact. We both bled a lot in the early days, just from changing water bowls! She was so territorial of her cage - not at all now that she trusts us.
She is now 8 months old and will go to anyone Dave and I hand her to because she trusts us. She is also flighted which means she has been extra extra good in learning what her world is about. She has never been forced to comply with ANYTHING.
This is the best piece of advice I can give you. Listen to Ra. If he is distressed and biting, cease what you are doing immediately. If he is not in the mood to learn step up, try again in an hour.
If he doesn't treat you with much respect, then you must earn it. This may involve going back to basics and just sitting beside him while he's in his cage. Talk, talk talk. About nothing, think aloud, read aloud. SMILE at him (they can understand facial expressions you know, and if all you do is frown and wince because he is biting you then you will be wary

)
Don't be afraid to tell him no gently, but firmly if he hurts you, but at this stage, do not punish him in any way or raise your voice. Dave used to pretend cry when Cal hurt him. Just like a puppy, Cal would stop and look at him in shock! I used to simply swallow the "OUCH" in my throat and gently take my hand away. This ALSO gave Cal food for thought. Because she was not so******ed, she was not sure what my hand was doing. She didn't associate it with her food bowl or treats, just the fact it was fun to bite lol. She never stopped looking shocked when blood appeared. Or when I had the cheek to take my hand away and tend to it lol.
Do NOT get anxious, do not worry that this is how things will always be - it won't. It may take a long time, it may take a short time, but you cannot put a timescale on this type of bond. It is to be earned on both sides. Do not show fear to Ra. If anything, indifference works best when a sunny bites lol. It sort of shocks them into behaving properly. It is one thing for a sunny to show a human they dislike them.....quite another when they get no reaction lol. Ra will come around if you take the time to understand bird mentality.
There are many, many resources on the web but you know, 95% of it is INSTINCT and of course, common sense. Noone can say "Here's how to fix this problem" because we've all been through it in varying degrees, but each bird is different. It is up to you and your bf to unwrap Ra's personality and find out what works best for you all.
I hope that helped and I wish you luck!
