So I come to find out that this HB9 that I've been after is in the "I don't want a boy right now" phase because of some shit that happened with her ex over the summer. She still thinks I'm the sweetest guy ever (took her to the hospital the other night). So should I play it cool and let her come to me when the time's right or keep at it?

If you're chasing her, she's already gone. Don't "be after" people, the way you think about things has an incredibly powerful affect on what happens in your life. Further, think about things from her perspective, what's more interesting? A guy that lines up for her affections, or a guy that is so busy living the adventure that is his life that he doesn't have time to line up for anyone.

If you're investing in her before she's invested in you, then if she wasn't gone to start with, she's gone now. Taking someone to the hospital, not necessarily a bad thing because nothing is, but I'm not going to lie, I have an image in my mind of what kind of guy you are from this, and from the standpoint of getting laid, it's not looking good.

If she has flat out told you that "You're the sweetest guy ever", don't plan on fucking her in this millennium.

If a girl is 'not ready for a boyfriend right now' she means she doesn't want you to be her boyfriend.

My advice, go with your gut and play it cool. What I mean is, divorce yourself from any desire for this woman, and set your sights on improving your life and enjoying yourself. In doing so you will simultaneously set yourself up to have the highest chance to attract her and be moving forward toward better opportunities.

Don't be a boy, be a MAN. The man. Sounds like you're already plummeting into LJBF territory. Avoid talking about it, but try to build attraction, rapport, and maybe some kino. The usual. A conversation about what you are probably won't be good for you. Also, don't be beta and be the nice guy, which is not to say you have to be a dick. In the meantime, I would not focus my exclusive attention on her, for fun and as a precaution.
