Regardless of whether you think the statute of limitations has run, do not talk to the cops or make any statements to them prior to consulting with an attorney or without having an attorney present. There are many guys in prison now because they thought they could make the cops go away by "talking to them.
If you are in college you should be smart enough to know how serious this accusation is. Hire an attorney immediately and follow his advise. Do not speak with the police unless your own attorney advises otherwise.

You are correct that the statute of limitations for sexual battery is 3 years. However, you don't know what statute the police are considering charging, which may have a longer statute of limitations. You also don't know exactly what date the allegations stem from and whether that date falls within the statute of limitations or not. It is never a good idea to speak with the police- it almost never results in the police believing your side of the story. Most people know the phrase "you have a right to remain silent, anything you say can and will be used against you." However, I saw a t-shirt the other day that is a little more accurate "you have the right to remain silent, anything you say will be misquoted and used against you." Do not assume that because you don't think you could possibly say something that might hurt your case, that the police or prosecutor agree with your assessment of your comments.
Depending on how you are charged will determine the statute of limitations. An example, if you are charged with sexual battery, a second degree felony in this state, the statute of limitations is going to be much longer than the four years you have alluded to. The fact that you were in a relationship with the victim is not an affirmative defense to the allegation of rape. Even married persons can allege rape. However, it is a good legal defense to show possible consent issue. I highly recommend that you do not speak with law enforcement without consulting an attorney first. You have a right to an attorney even if you cannot afford one the court will appoint one to represent you if you are formally charged.
