I've found the hard part in approaching isn't dealing with aloofness, or brush offs like, "I'm dating someone." The hard part is when they just stand there smiling and acting receptive, and then the pressure is on you to supply the conversation.
She calls you when her car breaks down. When she needs help moving. When some guy she's actually dating treats her badly.
You're the listener. The reliable one. The guy who would treat her so much better, if she'd just open her eyes.
She won't. You trained her to see you as the low-effort option — the friend who requires zero risk and zero investment. Every favor dug the hole deeper.
The "22 Rules" break the pattern. You'll stop auditioning for a role she already cast and become the man she chases instead. It starts with Rule 1.
