It is clear right from the start that the father, Jake, has never paid child support, and OP is the only one taking care of her child financially.
Not only that, but Jake doesn’t even look after his child when OP’s son is over at his house, and thus the kid gets bullied by his step-siblings.
OP tried talking it out with Jake, but when that didn’t work, she hired a babysitter, but that has obviously been quite expensive.
Jake, however, is not happy with this development and is accusing the OP of babysitting her son and saying that he isn’t going to pay for the babysitter.
