I (25F) have two housemates (18M and 18F). They were moving from the city I grew up in and needed a place to stay but I have regretted it ever since. Look they're okay but I made it so clear when they moved in that the way this works best it with communication. Like please let everyone know if you have someone staying over and there are any issues anything. But lately Fs bf has been staying over like 4 days a week (not letting anyone know) and M has been leaving a mess everywhere. I am out a lot as I don't really like them and don't like being there as I feel like I can't fully relax when there are others in the house. But when I get home there is rubbish.piled in front of the bins and crumbs all over the kitchen counter and sink despite the fact I have told them that this leads to move which we've had before and really need to be mindful of. M is also constantly late with paying rent and hasn't paid the internet in 3 months. Both of them constantly have people over without checking in
