My current boyfriend is absolutely wonderful and lovely, so hopefully I'll never need to take revenge out on him. But my ex boyfriend, well thats a different matter...
We got together on my 23rd birthday, he was absolutely charming, very good looking and played football for a first division team (so was a bit of a local celeb).
We were together for a few months and it was great - he spoiled me rotten, was always taking me to nice restaurants - and then I started to get that 'nagging' feeling in my gut that told me something wasn't right. He fell asleep at my house one afternoon, and I had a peek at his phone (naughty, I know, but my gut instinct told me to do it). Well, on his phone were messages from a girl saying how much she loved him, and how she couln't wait for them to be together, and a few filthy ones thrown in for good measure. So, I woke him up (not too gently I might add!) and asked him what the hell was going on. He told me they were just friends and she was going through a hard time - and I believed him (what a sucker).
A few weeks after all of this, I caught him hugging a girl in a nightclub - asked him who she was and he said 'Lisa' - I went up to the girl and asked her name, turned out she was the one from the texts. I introduced myself to her, she was quite shocked as she didn't know he had a girlfriend. One agaion, big arguments between me and him, I took him back.
I took him out with my friends one night, and he gave my friends little sister his phone number (thinking I wouldn't find out).
On bonfire night, we met up for dinner and went and watched the fireworks - he got quite twitchy and said he had to go - found out later he had arranged to meet his (other) bit on the side for a drink.
There were lots and lots of other incidents like this, he cheated on me at least 8 times (that I know of), but karma came and bit him on the ass - he caught herpes from one of the 'ladies' he slept with (which is why you should always, ALWAYS use a condom - thank God I did otherwise he'd have left me with more than bad memories!!).
The end of this delightful relationship came on New Years eve when I broke up with him - unffortunately he didn't take it too well and kicked the crap out of me - I had a broken nose, a fractured jaw, a cracked rib, black eyes...the works.
Now for my revenge...there were a set of keys to his car in my house - my flatmate and I let ourselves in, trashed his car and weed on the seats - gross I know, but what are you gonna do??!!
I then took him to court for attacking me, and got him sent down for 6 months (happest day of my life!).
When he was released (ironically, on my birthday a year after we first met) I put posters all around the town letting people know he is a woman beater - and that he had herpes...everybody knows who he is round here, so they had the desired effect!
The ultimate revenge is that now I am in a beautiful relationship with a man I adore, I have a lovely apartment in Spain and am very very happy (and I have a car that doesn't smell of wee!). He is single, still hanging round the local clubs trying to pick up women and living in a bedsit, his football career is over - oh, and he's still driving the wee car!!!
There have been other victims of my revenge, but I'm a lot more chilled out now - I was a feisty little bitch when I was younger, whereas now I believe in karma...! (Well, assuming my boyfriend doesn't cross me!)
Sorry my post is so long!!
