Let me tell you from advice, YOU CANNOT DO ANYTHING!!!!!!!! Sorry for the yelling but I needed it, still didnt listen, still tried to fix, spoil, love, blah blah blah, thought if I showed just how amazing I can be, how strong my NGS is, that she would just wake up one day and be like "oh, wow, I am such a selfish ass and I need to be with my husband that loves me etc, etc etc," Yeah, never gonna happen. Also if she dumps you but you feel like you need to win her back, she has 100% of the power, which is why she disrespects you. Trust me, I have severe NGS myself i'm working on.
You could win the super lotto tomorrow, take her to the Maldives or Bora Bora, buy her a ferrari, she might sleep with you, might even fake her happiness, but she wont ever respect you, and if there is no respect there will be no love, women are NOT attracted to men they have zero respect for.
So please realize that you cant do anything to fix this now buddy, just let her go, and see what happens. I finally got it after 6 months myself trying to "fix it."
