Ok, I understand your fears... So no legal advice, maybe some psychology. It is bloody easy to catasrophise - think of worst case scenarios and if you think about them long enough they become more real.
Even after 5 years, every time I have to see my ex, I have to focus my thinking and not worry. It takes practice.
Now the reality is, he has not been sent to jail. Good. Hopefully, he has learnt that there are boundaries, but the law will protect you. The first bit of trouble and you go back to the police, and because he has a track record, the cops will be quick to act. That should bring you some comfort.
