i had a break up about 9 months ago.My gf suddenly told 1 day that she wants a break up. i tried to convince her and made lot of efforts.We had relationship for 4 years and i did lot of things for these relationship.She recently got engaged with her brother only.Her brother had played a important role in our break up and not letting her to reconcile with me.I have stopped all sort of conversations with my ex. But since last few days my ex is trying to know about me.She requested 1 day to just inform her that whether i am fine or not... Why is she doing such? is it because she is feeling the guilt??..what i should do..i just hate her now...
