Amazing, U deserve a round of cheers already, for u've been so honest to admit ur mistake. we hardly acknowledge our flaw, but u've been so open to let everyone know tht u were the one who knowingly/unknowingly lead ur relationship to whr it is now. Men hardly say I dint give her enough love, they always live feeling high to have given enough attention to their other half. Rarely do we realise tht relationship is always evolving; it is an art which requires constant care and attention. It faces different kinds of challenges everyday which makes it tough to remain the way it began. Both parties needa have equal zeal and commitment for it to flourish. Thr has to be somekind of "LILL" bit of challenge.Perhaps u flooded her with too much of challenges and over the time period her tiny grudges cud have accumulated & made her tough to have unwillingly but finally say 'ENOUGH'. As I said earlier, love is like a sand-u hold it too tight, it slips away; u hold it too loose, it gets blown away.. Perhaps u held it too loose-it got blown away. Ur galfren mite have thought - she's been holding it too tight for just too long... Thr cud have been so many situations which, we, as a 3rd party could understand, but i wont just say MOVE ON coz its hard. At this time when u feel like its the end of the world, the only best thing to do is hang in there. U realised whr u failed. Hope it helps u in shaping a better lover within u. Good LUck n heres a song for ya from all we sajhaite frens.... " tell me whr it hurts.."
