How to tell my husband i'm pregnant? and that i think adoption is a good choice?

me and my husband aren't cut out to be parents, and i'm lterally not making that up whatsoever. i'm horrible with kids, i think they're messy and dirty and smelly, and my husbandis the same way. we just didn't want kids- ever! he had a vasectomy about a year ago, and everything seemed to be going fine...until i missed a period. (no, i didn't cheat!) i asked him to check up on the vasectomy at the doctors, (he was a little confused, but did it anyway) and the doctor told him it reversed itself.(i didn't even know that was possible!) fanflippingtastic. so, now i'm pregnant. any suggestions on how to tell him? and how to breach the subject of adoption? because he'll most likely suggest an abortion, which i am noootttt doing. i can't kill the baby, because its a part of me and him.
