My boyfriend talks over me and I'm going to snap at him.
What made you decide that you should snap at him?
I get furious when someone interrupts me.
You should calmly try to fix this issue. Snapping at them will only cause a fight.
I want him to know who's in charge around here. I'm the bitch, right? I will be the one who tells it like it is.
You and your boyfriend are in the partnership so ultimately no one is in charge. Snapping at others isn't helpful and will cause more discord. Him talking over you is rude and you should let him know in a mature manner that will resolve the issue.
