You could be in trouble. If you actually lied and filed a false police report, then you could be charged with perjury (a felony), or some other lesser charge. I get this question from a lot of people. Based upon your question, I assume that you are boyfriend and girlfriend and have some kind of a relationship. I then wonder, whether you are asking this question because you really did lie, or you don't want to get your boyfriend in trouble; that he actually did assault you. If this is the case, then you are walking a fine line as far as your own personal well being. If he assaulted you once, I bet he has assaulted you before, and he will certainly assault you again. You are not doing anyone a favor by taking the fall for this. If there are domestic violence issues, you need to take them VERY seriously as this kind of assaultive behavior generally escalates in severity.
