I'm seeing her for a month and a half. Last night, she slept over. She by chance met my mom, only reason for it was that she was awake when i tried to sneak her out when i first brought her home, and again when she came over, she was awake so they met each other.

We are FWB's

So this morning, when i tried to take her out, my brother was awake at the kitchen. When i heard him i showed of signs of panic that he might caught her, she noticed that. He didn't see anything and i let her out, everything went perfect.

Later that day she told me how me hidding her from my parents and brother just raised her shame, like she's someone my parents are not supposed to meet, like 'what bad can happen'.

Why i have problem with them meeting her and vice versa. First of all, they can be really annoying. What if they mention how she's my first(at 24), what if they mention something about me that could turn off, make me lose frame etc.

Also, situation with my brother, who he is. 32y old, insecure, self confident issues, know to throw temper tantrums. The guy who can make problem involving me just to get better in our parents eyes, so they could give him money. Actually, he's doubled persona outside of house and in the house with us. I think people don't know how actually he's insecure and what a cunt of a person he is. Example - asked me why I need watsapp when i have no one to communicate, 'why do YOU need that'? He used to make fun of me in the eyes of unknown people at the gym locker room so someone could pick on how 'alpha' he is. Typical AMOG kid, that who he is. What if he make some stupid comment, like 'so you're his first', or anything to lower my value in the eyes of other people which he likes to do. I don't have great relationship with my parents but good enough. They are weird people, depressed, i don't like spending time with them so introducing anyone to them inflict shame in me

With her, or any other women in the future, we are not exclusive, yet i think. How to proceed futher? What can i change except moving out? How to answer her this issue when i see her or text? To say that i have no problem introducing them to her but just that, also with everything from above about how they know to make uncomfortable and awkward situations?

Thanks
