School lunch, do i hang out with my bf?

Ok well me and my boyfriend are really shy and we both eat at different places at lunch. He eats in cafiteria with his friends, and i eat in a teachers cl room with my friends. I am too wimpy to go over to the cafiteria by myself.. and none of my friends will go with me. He asked where i eat lunch but he never goes to where i am. I want to eat lunch with him but what do i do? Yea i do have friends who eat right next to him but i dont usually hang out with them that often so.. idk what im supposed to do. Is he supposed to be the one coming to me? Or the other way around. --- OR --- How am i supposed to approach him and his friends at lunch?
