@Diest TKO,
I'm glad - because the more I thought about it - the more it seemed to me that she was being on the up and up.
I mean if she knew you knew her boyfriend - or that you guys traveled in the same circles-she probably assumed you knew she was going out with him.
Secondly - how embarrassing for her would it have been if you'd asked, 'Do you want to hang out sometime?'
And she'd answered, 'Well, I have a boyfriend...'
And you might have responded, ' I'm not asking you on a date- I just want to hang out...'- making her feel as if she'd been presumptious thinking you'd be interested in her romantically.
Maybe next time you can say to someone - 'So, are you seeing anyone right now?'
I don't think that's intrusive and it gets that little detail out of the way right away.
chai - in answer to your question - there have been times I hadn't wanted to go through the rigamarole of introducing a friend whom I knew was just a friend to me but whom I really liked- to my significant other. Mostly because I knew my significant other wouldn't have really given a crap about me being friends with the person, wouldn't have found anything in common with the person, and it'd be an hour or two of sitting there awkwardly watching the minutes tick by while all of us were uncomfortable- until my significant other would have finally said- 'Yeah well, I've got work to do - see ya later.'
What would be the point?
But our situations sound different.
