This bitch I swear. Boyfriend told his mom that she needs to quit going behind his back and buying his oldest daughter a ton of shit and to stop making plans with his ex without him knowing. She actually told him that she didn't need permission to do things with his daughter. WHAT?!? If it is on his time then she absolutely needs to ask, and if it comes to pick up/ drop off with his ex for their daughter then he needs to be the one making decisions with his ex, not his mom. Her and her husband are constantly overstepping boundaries and acting like they are his daughter's parents.
