She hasn't managed to do anything. You've just been too weak.

You talk about this as if you're somehow different, as if nobody has been there before - I've been in the same situation. Punching below my weight on the looks aspect, while knowing it's not right, nice girl, tried to break up and she was in a bad way herself. You're not a fucking charity. If you can't be with someone, stop wasting both of your time.

More so, stop being a pussy.

You know as well as any man that a woman's words differ greatly from her actions. It works both ways. You can't just tell a girl 'this is a terrible idea' or 'don't fall for me' etc. because your body is telling her otherwise. You're still there. Your relationship is one sided, weak and hollow. That's not fair on either of you.

Good call on Amit, but you're not in a position to give life talks when you're not taking others advice.
