Why does my dad keep leaving me?

He went to spend time with his girlfriend for the weekend or spend the night. I know he loves me and there for me. My cousins (males age 24) moved in 7 months ago and....yeah. I’m stuck with my cousins and they have their friends over. I complained to my dad, “Why are you leaving me?”
He said, “Girl knock it off. You’re going to be 18 in three months. Almost grown. You ain’t no five year old anymore. Your cousins are going to be here so... just stop. They got your back. Gotta spend time with my woman since I haven’t seen her in a week. Go ask your aunt if you can stay with her for the weekend.” Now I’m stuck with my cousins and his friends (three friends). I don’t wanna go to my aunts house. Stuff she does is boring 60 year old things even though she loves shopping and she is fun to hang with. I already seen her this week so there’s no need to.
