I’m going to defend your boy here for a second.
Being a single father to a little girl has to be so hard, I can’t even imagine it. When you have two little girls like I do you inevitably think about shit like what you would do if your wife isn’t around anymore. I’m guessing he has ni family and no friends nearby, except this big, mean ass bouncer roommate with a closet full of guns, and a never ending supply of you tube videos.
The entire well being of this little girl who doesnt know anything except her daddy is her whole world, and she shows it the only way her little mind know how, by being kind of a brat. Not something I’d wish on anyone, bruh. She’ll eventually be fine, at 3 years old hardly a thing matters other than she’s loved by daddy. Believe that.
Sorry you are stuck dealing with it, though. Must suck.
