I wanted to considering she was my best friend - stood up for me at our wedding and was also married herself.
I would shop for benefit fraud BUT would not stoop to something like paint over the car.
I tried to just get on with my life and live it well.
Sometimes it takes a while for it to come around BUT it does.
Not long after they had both left me and her dh - they had sadness in their families with deaths of members - unexpectedly and in terrible circumstances.
BUT for me - 14 years later i ran into them not having seen them for about 13 years and she looked like hell - he looked dreadful. They looked like life had beat the will to live out of them. She looked so dowdy, was very large - as was he and they looked like misery guts. I just laughed cause here was two people who only wanted to be together and that is all they needed to be happy and it looked like they had been serving a life sentence. They also were very vain with their appearances and so on. I just laughed and thought how life changes. I have wonderful dh and three gorgeous girls.
In fact if he had not given me the filthiest look I probably would not have recognised them or even looked twice.
I also found that they were ready to dish out lies as to why they had to leave their respective spouses and be together. I was a bitch and her ex was terrible. So why prove all their lies wrong. WHy let them say - 'see - told you she was a nutter/bitch/ hard to live with etc.'
Nothing to stop you plotting thoughts of revenge in your head or even writing about them. Then shred it or burn it and let it go. I did that too.
