I have a stepdaughter who is 8. She is spending the week with her mom this week. Apparently she thinks it's ok to come over to our apartment complex when she has my stepdaughter. I was bringing over my daughter to play, drama free, but his ex is over here too which equals drama. Does she have the right to be here since technically my stepdaughter lives here 90% of the time even though she's with her mom this week due to summer schedule?!?
