Is it wrong to feel like this?

I'm 36weeks pregnant and havent been feeling a bond with my daughter that I feel like I should be! people always ask my you can't wait until she gets here can you I just out on a front and say yea I can't wait but really I don' t know what to think my sis believes its because of the father but I don't know yea he did do alot to me planned her than left but thats life sometimes I feel I kinda was letting that get to me but I feel upset with my self that I try to have a bond with her but I have alot of other things on my mind I really hope its different when she arrives!
