Men lie
My boyfriend of 3 years just informed me that he had a secret relationship with some one from work about a year ago. He told me that it only went on for a few months, so there was nothing to worry about.
I asked him why did he lie to me for over a year now. His response was that he did not lie, he just did not want to hurt me.

That really sucks, sorry.
Not all men lie! You just got a piece of shit for a boyfriend…sorry. Find someone who will treasure you. I am not being idealistic either. people who cheat are the biggest bags of crap on the planet, and if they do it once they will do it again, move on….quickly.
