Hi
@Jazzy Bird! Sorry you are having trouble with Jasmine. I can imagine those bites very painful!
Hormonal times can be very difficult.
It's helpful that you know what you can and can't do with her. Keep doing the things you
can do successfully with her, such as grooming the pin feathers on her head and picking her up after a shower. Try not to do the things that lead to a bite, because it is only teaching her to bite more in those situations. At the moment she is giving body language to say she is going to bite (which is great as some birds don't!), so try to respect that to avoid getting bitten. I wonder if she could step up on a folded fat rope perch? Something like this. This is what I pick up Kobe (Pionus) with when he is hormonal. You could squeeze it together more so that the two sides support her:

Jasmine may have chosen your husband as her mate, but you can still have your own special relationship with her. The trick is to pair yourself with something desirable. I suggest training her to do something simple like targeting. This is teaching a bird to touch a target (maybe the end of a chopstick or other stick or toy) with a body part (usually the beak, but can be the foot) for a reward/reinforcer (a treat works well). If she is likely to bite, you can start off teaching her inside her cage - the bars with protect you. Whilst she has fun being successful at touching the target on cue and earning yummy treats, you also get paired with the whole fun experience. Win win! This is how you teach a bird to target:
Target training is a fantastic first behaviour to teach. It can be taught inside or outside the cage.

How is her diet? You could try reducing carbohydrates (pasta, corn, etc). Avoid warm mushy food too. Don't let her have access to any small dark places like boxes, drawers and cupboards.
