Ok, in my previous relationship, I cheated on my boyfriend when I went abroad on holiday, kissed another guy. I just got caught up in the moment and was flattered someone older liked me, also, it's the first time I'd been away since my brother died and saw my mum happy, so in a way, it felt like nothing had happened, and that I wasn't with my boyfriend who I'd met after my brother died. We'd been together quite long, about a year I think, but I was quite young and got carried away. I felt awful afterwards and knew I'd made a huge mistake, but I know now I'd never make that mistake again because I've learnt from it. I didn't tell my boyfriend until he broke up with me a long time after. I didn't think he needed to know, it would only have torn us apart, when I'd learnt an important lesson, which I figured was better doing it then, having only kissed someone, than 10 years down the line sleeping with someone 'cos I got caught up in the moment.
