How do you break up with your boyfriend if he threatens to put you in jail for mental abuse if you do?

What??

I'm pretty sure if your boyfriend is going to jail it wouldn't really help or make any difference if you break up with him.

If you want to breakup, just tell him that you don't want to be with him anymore and that you think it's time you ended it.

Note:

If this question is implying that the age difference is a legal issue (statutory rape) breaking up with him will only prevent future counts being added to the list of charges. Breaking up will not mitigate charges reflecting actions the two of you have already taken.
