Do you think it's wrong that my best friend's girlfriend wants to sleep with me?
Why do you think your best friend's girlfriend wants to sleep with you?
The other night she invited me home where I got a tight hug from her while he looked on jealously.
Even though nothing really happened when your best friend's girlfriend hugged you, you should still be careful. Because you should not sleep with your best friend's partner.
I don't know how to stop her from flirting with me.
You would ruin your friendship if you were to pursue a relationship with his girlfriend. Make sure to discourage her by telling her that her behavior is wrong and you won't betray your best friend.
