I think it was a mistake having our daughter?

Our daughter is 2 years old and she is a burden and my wife and I just can't have fun anymore. we have been changing diapers, feeding, bathing, carting her all artound everything. going boringh places, playing stupid games with her and agter two years we both agree that we don't like her very much. I told her last night that I am mad at her and I don't love her anymore so she's been ccrying and hasn't talked to me since. should i feel guilty for shipping her off to live with her grandparents or am I okay for doing what I'm doing since I know my wife and I are not able to give her what she needs since she's not a lovable person.
