6 months ago I found out my then boyfriend of 7 years had been cheating on me and when I confronted him he told me it was serious and he was leaving the kids and me for this other woman, she came with him to collect his stuff and basically told me in front of my children that the best woman had won and if I made a little bit more of an effort with myself I would be able to keep a man! Well 3 months down the line she ditched ( for another womans husband). I've just found out that her and her new man are having an engagement party I know the date and where its being held and I would love some advice on how to ruin her night.
