I would do anything for her when I said she means a lot to me. She isn't good with religious stuffs but deep down I promised myself I would guide her to be a better muslim. (Not saying that I'm holy or what) . I accepted all her flaws but sadly she didn't accept mine.
Then brother, what else can you do? If you see hope, and think you have a chance, then don't give up. if not, just move on or just be friends :)
