Why did my ex wife leave me?

the question is killing me everyday. i dont know whether i'm still in love or hate my ex wife. she left me 3 years ago, just after she had got a job in kuwait airways. i had always tried to be a good husband. no fight, no smoking, no drinking, no other girls issues. and it was because of me why she got that job... long story short, she never contacted me afterwards, denied to meet me and sent the divorce letter through his father. i'm now re-married to a beautiful girl and we are blessed with 6 months baby boy. but still i cant get rid of the question. infact i broke my head over it and cant have much headway. please help.
