Should I be allowed to have my partner over every now and then?

Anonymous
Myself (22), my brother (26) and his girlfriend (23) want to rent a house together. My brother’s girlfriend has a 5 year old kid with someone else and she has her kid every second week.
We will all have our names in the rental agreement.
I got told by his girlfriend that I wasn’t allowed to have the guy I’m seeing over in the week that she has her daughter around. I’m not allowed any guy friends over and even friends in general when her daughter is around for the week.
Now myself, my brother and the guy I’m seeing we are very “traditional”. We have morals and values etc. I know for a fact the guy I’m seeing would never in a trillion years harm a child, never ever. I mean when he has come over to my house, we get home late and sleep, stay in my room unless we use the toilet so her daughter wouldn’t and has never even see him. Usually leave by morning for breakfast and everyone is gone. He’s always fighting for what’s right and is one of the softest guys I’ve met, he reminds me of home and I feel safe.
Yet she still says no to me. I have no clue what to say or do. I feel I’m being looked down on like I can’t even make choices in my own home
