PLZ HELP? in love... But i have guilt! Killl me now?

You should not feel like its killing you. You didnt do ANYTHING wrong. Neither did WB! He has feelings for you, and you have feelings for him. Is he still dating her? He shouldnt be. Thats the problem here. You and him should be dating!!!!! If this girl is moving, then your "friends" will forget about it in no time. You'll be fine!
