You know, I have a lot of guy friends, people i love but would in no way want to start a sexual relationship with. You would be suprised how often I have had to curtail contact with them because others, from my mom to the guys' new in-laws, whatever, can't picture contact across the genders as anything except sexual. That seems to be the defining factor behind relationships in some peoples' minds. I'm surpisedthey can hug their kids with a clear conscience

You did the right thing. You can't do anything about jealousy, or why she decided to come back at you (I mean, Chris, if she needed his help to decide whether or not you were flirting, something there is not right!). Knock the dust off your feet and don't look back! Huggggsssss
