Ryan, this post is so very inappropriate. You have shared personal, intimate details about this girl's life (and MEDICAL history!) without taking any care to de-identify the information. Firstly, I'd suggest removing the link to the video at the very least. It is unnecessary for getting advice here.

Now, onto my advice. Love isn't this hard. You're not in a film. This isn't When Harry Met Sally. It's not going to end well. The relationship dynamic you have outlined here is really toxic.

Who knows if she's leading you on or is actually accepting of your 'friendship' and gets confused when you regularly withdraw it out of frustration. I'm not convinced you care for her beyond an obsession or fantasy you've created. You're frustrated because she doesn't comply with that fantasy. And do you know why? Because she's an actual human being. The language you are using about women, your friends, and how you relate to them are disrespectful. Leave her behind and focus on developing mature, respectful relationships. Pick a girl who is actually single for starters. And then try to relate to her on a human level. The relationship part will develop more naturally. And wouldn't you actually prefer to be with someone for whom there was no doubt? I wouldn't want to have to convince someone to be with me.

And I speak from experience. I had a similar dynamic with a guy when I was about your age (I was probably coming more from your perspective). I cringe when I think back to that time. He clearly wasn't interested in me like that and it was so much better for my mental health - and my love life - when I moved on. And now, more than 10 years later, we're actually genuine friends again.

You've got the rest of your 20s ahead of you to have fun. It's such a great time in your life. This...situation...you're perpetuating doesn't seem like the most productive way to spend it.
