What are you doing flirting
with someone when you have a girlfriend
?? What is wrong with you?
Also, it's completely inappropriate when it happens at WORK!
Also, suggesting you'd like to see her body? What? Who says that?
You're over the line, IMO - way over.
She was culpable, as well, but geez - what idiotic behaviour! Think of where you were wanting to see this going. If I were your g/f, I'd dump your sorry ass.
Completely unacceptable behaviour on both of your parts.
