OK, I didn't take the time to read all the posts. And, I might have had a few beers. But, you should have posted a fourth option. Stay with her AND sleep with new girls. Just make sure (since you're only a freshman) not to sleep with ugly girls, because it will ruin your reputation. If you only sleep with hot chicks, then other hot chicks will want to sleep with you. Young girls are stupid. Use it to your advantage. You shouldn't be mature enough yet to care.
