One of my house mates out of no where over the last few months has taken the “Alpha position” of the house. For some reason he seems to have a disliking of me and can often sway things against my directions.

Back a few months I was up their as one of the leaders of the house. Now I’m possibly seen as the boring one due to my college course being intense and me focusing on that. Hence my wild times have slowed down

How can a retake my position at the top, or atleast feel more comfortable/ not give a fuck what he thinks in my own house.

His passive aggressive bitchy as behaviour is so draining and his bitching is too. Despite this they all still like him.

Any advice?
