<human>: To start things off, I've been with a girl for 2 and a half years. It's not that significant when compared to some people, but to me, it has been quite a while, and we haven't really faced many issues up until recently. See, I live in Iceland and she is from the UK. We're both in college and we're both finishing up, and with that said we haven't gotten that long till we can actually move in together. But her patience and the distant got the best of her, and she ended up kissing another guy. I do admit that we hadn't been as close as usual, and we were apart for more then the usual amounts. But this kiss destroyed me, and it destroyed her. She told me that she regret it, and that she doesn't have feelings for him, but then she said that she couldn't guarantee this from never happening again, and I'm really worried on how I should react to this matter, as it almost tore us apart and it really made me lose a lot of trust in her.

Can you give me the gist of the text in a nutshell?
<bot>: Long term with a girl, not long till we can close the gap, but her patience ran short and she kissed another guy, need advice on how to handle the matter ?
