There's no fool like an old fool. Don't let a boost to your ego ruin your life!
Yes you did the right thing - but was she flirting, well that could have been just an innocent happening on her part. If similar events happen, then yes - I 'd say she be flirting.
Yeah - I would say she like you and is being nice. If you do accept the offer, have the wife join you. At least this way she knows you are happily married.
Send her my way. I need a girl friend like that.
Maybe she was, but also as you're colleagues she might have felt comfortable asking you for help as a friend...it's likely that there was a little flirting going on too, not neccessarily that she wants to steal you from your wife but maybe "safe" flirting because she knows you're married and wont act on it...
She believed you to be a gentleman, and needed assistance. Don't over think it. She'll respect you infinitely if you continue being respectful with her.
