Ellie Camm, 27

While I was a student, I started dating a guy who told me he had a friend called George who was in love with him. I thought it was a man, but it became clear it was a girl. He said they had dated but were just friends now.

I eventually met Georgie at a party, and we got on straight away. I broke up with that guy a few months later, but Georgie and I became inseparable. One evening, we started chatting about our mutual ex and worked out that he had been dating both of us at the same time. He had even got me to leave one morning so she could come over that afternoon. I wasn’t angry with her – she wasn’t to blame.

Last year, we moved into a flat. I feel I’ve found someone I was meant to be friends with. There’s nothing I couldn’t tell her.

I was nervous before the party, knowing I was going to meet the girl my ex-boyfriend had picked instead of me. But when Ellie and I met, it was like finding a long-lost sister. We instantly became close.

Then we found out he had been cheating on us both. I believe things happen for a reason. Ultimately, I wouldn’t have met Ellie if this guy hadn’t been in our lives: the experience brought us together and made our friendship stronger.

I’ve never been happier living with another person. When she went on holiday, I wandered around the flat like a lost puppy. Everyone who meets us can see how close we are. We go to bed sometimes and text each other through the wall.
