Hi toni:
Don't take this the wrong way but you can't "muck about" with the system. You obviously saw fit to complain initially about your boyfriend's actions and expected the Police to act accordingly. Which they have done and have clearly spent a lot of time in doing so.
The fact is that when someone makes such complaints and allegations it triggers mechanisms in the criminal justice system which is not only manpower intensive but also financially expensive to the public purse as well.
Would you feel the same if it had been some total stranger you'd made the complaint about? I'm positive that the Police would have advised you from the very outset what all the possibilities would have been? And that would have been the time for you to discontinue this process, not now when it's about to go to Court.
Your "wishes" are not what legal processes are about. It's more a question of alleged offences by complainants (like you) being investigated, evidence gathered and, if need be, to prosecute offenders.
And, yes, you can be compelled to attend Court. A dim view is taken of those who waste Police and Court time.
