Already, 2019 is becoming a bad year....

It's the first day of the new year and already things are going to pot. From 12:00 pm to 2:00 pm, my mother and her boyfriend, (who I think is more of a father than my dad would ever be), had one of their biggest arguments to date. It started with my mom wanting to talk to him while he was reading the paper on his phone, then escalated to a huge argument over things like how Niall (that's my mom's boyfriend's name) acts like a dictator, feels like he does not get enough gratitude for things he does around the house, and gets a little obsessive over the tiniest things like posts she makes on Facebook while Niall complains about how most of the time when he comes home, my mom is often angry or sad about not doing things, how she wants stuff done in a certain way, and how she takes advantage of his time (according to his viewpoint). Now they are considering breaking up and my mom is on the verge of considering it. But the truth is I think Niall is the best thing to happen to her as well as me and my brother, too. Also, and quite selfishly, I may add, he pays for the Netflix and Hulu we use at our house. But the most important reason why I don't want him to leave is, like I mentioned before, he is like a father to me. What should I do?

By the same token. You're an adult and you've got to make your own decisions.
Don't mentally defeat or beat yourself.
So here's my advice; if your mother wanted Niall to do some action around the house, then while they're calm down, tell them to set-up some kind of rules that they both can agree to do. Some kind of actions that can only performing during certain hours that Niall can settle in and some actions for your mother to settle in.
And be strong.
