I think I would be more concerned if you did immediately trust her.
I know there have to be some great qualities about her. However, those are some significant and very recurrent red flags.
I'm particularly concerned about how you say you two are enmeshed - being enmeshed makes holding healthy boundaries extremely difficult, for both of you. The fact that you changed (were dishonest) about the timeline of a crime committed against you by someone else (possibly a criminal act on your part if you changed it in a reported to police, and if not, still possibly destroying of the case if it gets prosecuted), and something that's denying her truthful information about you. While you did it in order to save the relationship with her, it is also a sign to me that no matter how good her good qualities are, this relationship isn't healthy for you in this moment:
You are bending your own values to make it work. There is compromise in every relationship, but it seems like you are both apprehensive about being honest with each other.
Boundaries are about more than saying no, but also following it up with action on your part if and when someone else walks over them.
It's not wrong for her to have as many sexual partners as she has had, or for her to feel accused in a disagreement with her boyfriend in the middle of a possible breakup - but her actions about the condoms and neighbor is a little strange and concerning. It just seems like there is something she is really struggling with too.
I think an honest conversation is in order - about what your stance is on sex is in order, especially since you have been recently raped, and letting her decide if she can jive with it or not. It's only fair to you and to her.
Trying to trust her right now with sexual matters without all these red flags but with unresolved/unprocessed sexual trauma still in the mix is also a huge task - I think you both need to think through if you are up for what it is going to take, and I still think it will need to include some therapeutic support, possibly for both of you.
Just my thoughts though - you can take them or leave them.
