Is this cheating? feel so guilty/:?

Well lets see if u didnt think it was cheating and u thought that this was all an innocent mistake then why havent u told ur boyfriend? If you were "truely" on a break then why are you hiding it? because deep down u know if the tables were turned u would view it as cheating.. because it was cheating on your bf.. and the excuse about your grandfather is lame cause one can say if u were that distraught why were u out partying and drinking instead of being with your grandfather if you were that upset .. so dont excuse your actions be accountable for them...
