Lunch table question..?

So today was the first day of sophmore year and during lunch it was just my friend and I alone at the table. Most of the people who used to sit with us got moved to another lunch time. I'm not really that great friends with her, and shes kinda clingy. And when I suggested we sit at another table, she said she was fine with it just being us two and wasnt interested in sitting with anyone else. I want to meet more people, and I prefer sitting at a crowded lunch table, but how do I do this without leaving her alone? I think im ready to completley break off from her anyway... but I feel really bad about it. What should I do? Last year I was new and I didn't have any friends and I want to meet more people this year. (But thats a whole nother story) Thanks
