Ok, I think I'm beginning to understand, please correct me if I'm getting this wrong.
Words don't come easily when we are stressed.
I'm guessing that you haven't know this girl for very long?
It can be difficult when we have to rely on people we haven't known for long, and who don't know the background info, for example, that you were already late for curfew.
It's good that she is reaching out.
Do you feel up to meeting her for a coffee and a talk? put some ground rules in place first, that if either of you start to feel stressed, that you say so and can both take a rest to calm down. that neither of you will let it get heated.
If you are each able to talk and each see where things went wrong and could have been done better - good.
If she can't own her mistakes, don't try to make her own them - keep calm, and just acknowledge to yourself, that she's perhaps not the best person to have to rely on.
Be careful about the cops. I make no secret that I have a very low opinion of the institution of statist police, and a very low opinion of many (not all) of the individuals who wear their badges and costumes, and claim to have special privileges over the rest of us.
What cops are portrayed as being on TV, and what you actually get in real life, can be very different things. At worst, you can get a bunch of [anabolic ste]roid raging thugs, who expects to enjoy the special privilege to be able to beat hell out of people, or even to murder them, with absolute impunity. Compare that to a member of a street gang - and the street gang member expects to face the full consequences of the law if he is caught. the cop fully expects to, at worst, get a few days "suspension on full pay" ( a paid holiday).
No one is safe when cops are around, but if you are poor, have a noticeable minority accent or, are a member of a visible minority, then be extra careful.
Good luck, you've got yourself somewhere safe, you're making progress.
