Ouch... Damn; of course, there's logic, and your friend was... dumb. What kind of friend tries it on their friend's girlfriend, or if it's female, boyfriend? Seriously? That's really stupid.
Like I said, going for shy cuties from now on who seem to have their head on straight, no more beautiful ones with their heads on loose. They're the ones that seem to like the sex starved bad boys anyway. My friend's ex girlfriend was the same way; he thought she was pretty (I didn't) and in the end, she ended up kissing another guy in front of him and well, things didn't go well for him after that. He was so obsessed with her, wanting her back and everything, and I told him, "She's no good for you." She's not very bright, either, as she has a baby on the way and she smokes, drinks, and is a pothead. The baby's father is the guy that she kissed in front of my friend. Talk about drama.
