I met K in our first year at university. We were both doing the same subjects and, after a night out with her and her boyfriend, I quickly became close mates with her boyfriend’s friends. As such, I started seeing a lot more of her.

Cut to nine months later and I was dating a friend of her boyfriend. K, her boyfriend, myself and my boyfriend found a cheap house to share and all moved in together. K was very intense. She wanted to know where I was at all hours of the day–if I missed a class she would call me non-stop for an explanation. Then she started “Single White Femal-ing” me. She cut her very long blonde hair the same as mine – very short and dark. She’d “borrow” my clothes all the time. She’d mimic my accent.

Suddenly my boyfriend started avoiding home. We both had part-time jobs to supplement university and he would get home much earlier than me. He started going to the local pub and waiting there until I finished work. When I asked him why, he confessed that he found her “creepy.” I stupidly thought he just didn’t like her.

Then one night I came home late, and was standing outside our house on my phone so as not to disturb my roommates. As I stood outside I watched through the front windows as K came downstairs to find my boyfriend asleep on the couch, sat next to him, slowly crept closer to him, rested her head on his shoulder, put her arm around him, and eventually lay right on top of him, as he snored through the whole thing. When I went inside and asked what she was doing, she pretended to have just woken up and claimed they fell asleep watching TV together–despite the fact I watched the whole thing!

My boyfriend and I moved out a month later, after her she stepped up her campaign to “get” him. As a post script, after he and I split up she claimed she had cheated with him a few weeks previously. Sadly that lie ruined only her own relationship, and my ex, her ex and I remain very good friends to this day.
