This is a dilema. My best friend's girlfriend won't let me be. She keeps calling me and complains bitterly about my best friend's constant cheating. Anytime she feels down she runs down to me seeking companionship. The most shocking part is that she has passed the night in my house several times( but nothing don happen oo) and wants me to keep it as a secret from my friend. Guys, do you think she is up to something fishy, and if she is what should i do?
