I get upset over him all the time; I need advice please!?!?!?!!?

Well the reason he is ignoring you is because you gave him a rose, admitted to it, and than the next day acted as if you regretted the whole thing. Dont you think it would hurt to have someone do all these nice things for you and then look away. from now on when you see him in the hallways say hey, and i think you should tell him how you feel in person. fb just isnt as meaningful and he could send that to whoever he wanted
