Wife lost love feelings

Hie guys, i am a guy aged 31 married for 3 and half years to a 24 year old lady. We have a two year old kid together. The problem is during this whole period my wife used to complain that i dont show her love and i dont talk to her. This was for sure becoz normally i could give her one word answers. She tried to give me some books to read about marriage, i could read them but nothing touched my heart. I used even to urgue with her in public and show no remorse.

She has been so paient, and sometimes i woulkd ask for forgiveness and she would forgive me, but then i would repeat the same things. We could sometimes travel in our car for a long distance with out talking. To tell the truth I love her but i dont know what was happening to me to treat her that way. She would sometimes say she is staying just becoz of the kid, but i did not take any action. Sometimes she would cry the whole night and i would not change or act.

Just recently, 31 may we had any argument and i shouted at her, and told her, that the way i do thats how i show my love. I told her if she cant handle it she should go and look for a boyfreind. That day everything turned upsidee down for me. She told me that she lost love and sexual feelings for me long back but she was just having sex with me for the sake that we are married but she doesnt feel anything. If i touch her i will be like i am boring her.

My question is, now i have realised that i messed up things on my own, and to her she is trying to have love feelings but they are gone. I still love her, HOW CAN SHE BRING BACK THE LOVE FEELINGS AND THAT AFFECIONAL LOVE FOR ME. PLEASE HELP I NEED HAPPINESS IN MY MARRIAGE.
