Confused

Sometimes I’ll ask my boyfriend if I can stay over if I’m hanging out at his house and he’ll tell me “it’s too late to ask. I need a day in advance.” Yet today he says he’s going to ask after he’s off work at 5:30pm? You know you can just tell me no right? You don’t need to sit there and make bullshit excuses. I can take a simple no 🙄😒
