I miss my ex

I saw my ex-girlfriend today, in one restaurant, she is drinking fanta with her new boyfriend, and when she saw me drinking milk shake.
she told her boyfriend that she need milk shake, frozen chicken, fried rice, pizza, chips and salads, her boyfriend quickly ordered for it.
I know that she is asking for all that just to show me that she have been living fine, as a cool guy, I just packed and watch them... boyfriend suddenly went outside, in the name of urinating, I already know that he is running away, but I keep quiet.. Now the kin bae is through with her enjoyment, and she start calling his number, but is switched off, and she have no money.
She keep on starring at me, but I was busy drinking my Drinks, not long the waiter came for his money, and she was just there crying like a baby, when the restaurant owner came.
The conditions given to her is to pay her bills, or keep washing plates and peeling the potato till when they're satisfied, the bill is up to #8,000, I have the money, but I can't pay for her, cause she broke my heart.
As am posting now, she is still washing plates,
Should I help?😑
