There's a reason why most divorces happen: former couples realize they don't get along very well. And when that happens, there's always the chance that things end up messy. And it's always worse when kids are involved.
A Reddit user named AdmirableShallot155 opened up about how, after his own divorce, he ended up paying for more of his son's expenses than his ex-wife does. But the tables turned when she was responsible for paying for the son's dental surgery. Now, he's asking AITA if he's in the wrong for refusing to pay a cent.
