i feel u my friend.... it happened to me as well.... in a very same situation, ive been there already, and i tell u, revenge is not the answer. the more u think of sumthin like that the more u push urself down and will just hurt u more.
even though i know wat u feel right now, no one can stop u on wat u wanna do.
solution? just be happy na ur single again, free urself from burdens like going out with ur kid or think of anything that would divert ur attention. it may not be an immediate aid to ur wounded heart but i tell u, ull be thankful sumday.
this is how cruel our life is......
its just a good thing na im done with it, and already moved on... even though im still single as of now, i didnt regret anything, u know y?...... becoz i see the beauty and importance of my life more than anything else... love urself bro, and u will find peace in ur heart....
