I'm sorry to hear about your sister's death...may she rest in peace ! On the topic : My friend its quite evident that she was a gold digger...she used you and then discarded you when she found a better sucker ! She played with your genuine feelings to earn something of it...so think of this as a learning experience instead. At 25 you've got plenty of time to get married and do all sorts of sh*tty things with your life....but for now concentrate on completing your Masters and your immediate career plans kiyun ke bhai aaagar jaib mein koi dhellla nahin tou koi baap apni beti nahin dai ga aur na heee koi beti aap seh pehlee chakar chalai gee ! Just as most of us men, including myself, are complete arsehOles....most women out there are ugly in their ingenuity, superficial in their beauty and heartless in their desires....so don't sell your self short. Tou cheetah hai....suun rahaa hai cheetah ! So Don't you dare sell yourself short because you have no idea how priceless is someone who actually cares and you clearly do ! For now just concentrate on making something out of your life and the rest will follow through !
