She also bought me few things though I never asked,i was impressed and also liked her and trusted her,l alway tl her I m not yet settled with Job and I need my parents approval to marry anyone, in the end she said to her mother that everything did by me and I too loved her alot.I literally never loved her from heart she continuously used to text me and calls me at one point i used to get vexed and talk gently to her,she send her parents to my house and try to intimidate us.i don't want to marry her because of her true nature that revealed few days back.Their mother is threatening me that you have been in love with two years etc but I never had intercourse.
