How do I kick a cheating GF out of the apartment when she is on the lease?

Im in a bit of a pickle here. My girlfriend has been cheating on me, and I just found out. We moved in together 5 months ago. She is on the lease, but has not contributed any rent money. She payed for a few groceries and a minor fix on my car, but thats it. I cant stand to have her in this apartment, but she wont leave. What can I do to get her out?
