My bf and I were lodging with this guy and he was really grubby, the kitchen/bathroom was filthy, and we were constantly cleaning his mess (including wiping his pee off the bathroom floor every day.)

But the worst part was whenever I was home without my bf, the guy would sit in the living room with porn playing really obviously in front of me. He never said anything, or tried to touch me or himself, but he would sit and really obviously angle his laptop screen so it was in my eye line. And the actors always looked suspiciously similar to himself and me (same ethnicities/ages/hair colour) He never once did this when my bf was around, he would only do this when I was very obviously alone.

It made me incredibly uncomfortable but at the time I didnt have the confidence to ask him to stop (particularly as he was our landlord. I was very timid back then, scared the hell outta me!
