Roommates boyfriend keeps coming over and staying the night when we don't know about it.
I'm 19F and this is my first flat with people I do not know. At the beginning of the year a rule I pushed for was to be informed with whos in the house, like send a text if someone is staying the night or coming over. The flat agreed and it was fine until one of them got a new boyfriend, she's stoped telling us so I could be upstairs or in the living room and this random guy keeps showing up. It's making me really uncomfortable and I have spoken to her and the landlord.
Am I just over reacting and it needs to be something I get used to? He doesn't talk to any of us (like say hi when he comes in) and takes over the common space and even goes upstairs which is a girls only area. With the rise of student attacks recently in my country (New Zealand) I've been a bit paranoid and want my house o be a safe space.
Looking for some advice as I'm not sure if it happens in other flats and I'm over reacting.
Thanks :)
