Caggie Dunlop is a "commitment-phobe".
The 'Made In Chelsea' beauty - who began a brief relationship with childhood sweetheart and co-star Spencer Matthews during the Christmas special of the E4 reality show - explained their romance only lasted the duration of their festive break in Finland because the pressure from viewers was "overwhelming".
Asked how long her relationship with Spencer lasted, she said: "Just the duration of the holiday. It was hard. Not only did our friends get involved, but the whole country had an opinion and that's quite overwhelming when you're trying to start a relationship.
"I'm a commitment-phobe. I'm one of those people who, when someone doesn't want me, I'm like, 'I love them,' and then when they do, I'm like, 'No, I don't want you any more.' I'm a really difficult girl."
The 22-year-old singer admitted the couple's initial romantic liaison was "fuelled by Jägerbombs", and Spencer warned their 'Made In Chelsea' co-stars not to put pressure on her, as he knew Caggie would eventually run away.
Caggie added in an interview with new! magazine: "Finland was fuelled by Jägerbombs and was this crazy, surreal place. I didn't ever think it was going to happen but it just did, and as soon as I got back here, more people found out, and then more pressure was on.
"Spencer was like, 'Don't put any pressure on her, she's going to run!' It's one of those things with Spencer. We'll always have a bond, we have so much chemistry and we do have this connection. We have a lot of love for each other, but it's not what people think it is."
'Made In Chelsea' series three is on E4 tonight (02.04.12) at 10pm.
