"A big question I have is how do I approach the situation if she says she is going to go out in a day or two? I don't trust her at all right now.... but restricting her I think would lead to even worse actions or feelings."
Jake, you need to let her go and not question her about this. First, there really isn't a thing you can do about it and second, it is not helping matters, at all!
Trust your instincts here regarding leading to worse actions or feelings.
