What Can Be Done For My Wife's Behaviour Towards Me ?

Hi, I am 30yrs old and throughout my life i have been lonely. I have no siblings and the only child of parents. I recently got married ( 6 months ago ). Yes i was Love marriage and affair went 3 years before getting married. I was so excited to have someone that would belong to me, loved me only and would give me attention love affection ... But this never happened. My wife ( 23yrs) came from a big family ( having 6 siblings ) and throughout this time she has been missing them, preferring them and giving them more time than to me. I am so broken to feel this reality that she does not love me the way she did before. She wlays tries to make her way to her home ( 4km from my house ). And she does not even feel like missing me .. whereas i do miss her alot when she leaves me for 1-2 days. I am so much emotionally attached to her that i always want here to be in front of my eyes. But at her part she does not bother alot. I feel that why am i so much emotionally attach to her, and even if i try to dis-associate from her like avoiding her or talking less. I cant do that. But for her its a piece of cake. She stills look cheerful with her friends and siblings but never have shown true cheerness for me .... Please help me, i discussed her with all this but she said that i am being to clingy and over sensitive. Why cant she understand that i need time, good quality time with her so that i call fill up my past years gap of loneliness ... It seems i will never me able to fill up my inner space and will crave for it till death....
