This happen to me four years ago, i had been going out with my girlfriend for fours years, in the fourth year things started to go awry between us, i don`t know why. She started to go out more often with girls from work and leaving me home to baby sit her six year old son,we get on well with each other. This had been going on for six months, things didn`t feel right. Then out of the blue i get a phone call from one of my mates i hadn`t seen in ayear, hed been overseas, he wanted to hook up and meet his latest girlfriend. So friday night came and i headed into the city to meet steve and co at a cafe in lygon st. It was pretty crowded, but found my way to the cafe as i approached the door i looked in to see where steve was sitting, low behold i see my what i thought was girl sitting hand in hand with steve, i had the biggest gut wrench in my life, i turned and walked away from the cafe , with my mobile phone in my shaking hand, i called steve making my apologies and telling him i`d catch up with soon. When i got home iwas back in control of my self,the only thing on my mind was revenge, so i called up a very good and close girlfriend and told the whole thing to her, she came around and things got out of hand, but what the hell i thought, we were spread all over the couch arms and legs everywhere, I was actually really enjoying it when there was a loud slam of my door and a loud shrill voice yelling what the fuck am i doing, and how could i betray her so badly. Well you can imagine what a women scorned is like , yelling, punching and kicking of me of course. Until my friend turned and replied- 'what do you care, your sleeping with one of his best friends'!!!!! She had just stood there shaking with a nervous/ i`ve been caught in a lie look, how did you know the reply was,'I was there and saw you, so who was the betrayer? this led to a long conversation about needing some spice in her and my love life, which we got with a helping hand my close girlfriend, now things are better and the sex is fantasic between the three of us, its been two years since the incident.
