Lies

id been with my bf for a long time, and he finished me, just out of the blue, i really wasnt expecting it, anyway, he told me it was because he liked this other lass more than me, this lass happened to be one of his close friends, but he kept telling me he still loved me, and said there was a chance we could get back together, i feel like an idiot now, it was nearly a month ago now, but i have to see them at skwl everyday, it kills me, i managed to hold it all in, but now i just cant do it anymore, i break down in class, and he just think im attention seeking, but wont deny he still cares for me. help?
