<human>: My girlfriend told me that if she was single she would sleep with her best guy friend, but that they respect each others relationships. I've met him, and he is a really nice guy, but it just bugs me thinking that she said she would still sleep with him if she was single. I'm not sure why. Should I worry?

Can you give me a shortened version of the text?
