You sound far to young and certainly inexperienced to take on a horse that is in ned of very strict handling.
She needs to be tacked up, a lunge line on her and made to keep to the outside of the circle. If she comes in then you crack the whip at her and if she still continues to come in then you give her a good lash with the whip across her front legs hard if you do it hard enough she will spin away and she might kick out so you give her a couple more across her back legs again hard.
My experienced opinion is that there is nothing 'good or cute' about her when she is like this.
LOL she really not good and cute like this >.<
But other than that she's perfect
It's just that if I will use the whip she will get on two legs and
And I really don't want that to hapen, I have talked to a
Trainer, and when he lunge's she doesn't do enything wrong
And I just don't know how to handle her...
That's not good. Let her kick & buck if you can't safely stop her, she'll get tired. If you've left her alone or stopped when she acted up you've taught her to do that, not that you meant to, of course. Just stay out of range.
The next time she tries to run you over make her care about the whip. She can & will hurt you if you don't show her you mean business. You don't have to beat her to get your point across.
but if I will let her kick and buck she will hert someone
If it's me or if it's someone els
I will try to video it and I will uploud it
Then maybe you guy's will see better the situation
