One more thing you have to remember YOU PICKED HIM!!!
What, you couldn’t change him to the way you thought he should be. And one more thing, even though you knew your ex was a POS you decided to have 2 kids with him. But that’s not all, you the realized you can’t change the sob so WTF since you have 2 of his kids now he should give you thousands of dollars a month for the next 18 years!!!
