Hey ladies this is my first time posting about this ive seen a few posts about there SOs family well i am curently going threw the same thing.

So today i was sitting at my SOs parents house with my boyfriend and he has 2 kids from a previous relationship. Well my boyfriends daughter wanted milk so she got herself a glass of milk she chugs the milk and washes her cup she than goes in the fridge and wants juice so i tell her no cause she just chugged the milk on purpose an she can wait. Well my bf told no to. His dad than proceeds to get mad at me and goes leave the damn girl alone if she wants juice let her f*ckin have juice. I go no she just chugged a whole glass of milk shell than complain in 5 min her belly hurts. Than his mom said something like oh grandma doesnt need permission to do things with you gies and that goes for your baby brother in her belly too i just sat there like confused... i was very pissed off.. she than texted me the other night and goes what are u getting him for his birthday? I go im not to sure yet i gotta come up with something and last year we had just moved into our own house and we had to pay all the bills up front so i didnt have alot of extra $$ at the time but i made up for it this xmas.
