I'm going to unset my gfs alarms so she would miss work and sleep in with me.
Why would you want your girlfriend to be late?
She's been stressing me out lately and I would love to ruin her morning.
Manipulation is more problematic, and may even be abusive, when it is part of a systemic attempt to control or harm another person. You should instead schedule time that works best for the both of you to be together.
Well, what's good is that she's late and still sleeping.
Would you want her to do the same to you?
