I would have absolutely no control over what she does and rightly so, you're her partner not her carer. If you're worried about her getting off with someone else then you shouldn't be in a relationship with her without that essential trust and respect between partners. If you're concerned about her getting hurt again then I can understand but as long as she has reported it, has spoken to the appropriate people about getting past it and feels that she is ready to get back into a normal, happy life then there is absolutely nothing wrong with that.
