Cant help myself from pulling away from my child dad..so much has been done during this pregnancy that i cant see how i can even get past it. Im not attracted to him, i dont kiss him nor do i want sex from him, i feel nothing when im around him just feel like im around a stranger. Maybe this relationship is only lasting for the sake of the baby.
