hi celticmoon!
we told our closet friends and family as soon as we found out we were way to excited to keep it in!
i can totally understand your delima my DH father is just like your dad! he has never cared about us at all so my DH never told his parents straight away and when he did we never heard from his father!it is an ongoing battle with his family!
all i can say is just be really positive as it will rub off on bub! and tell who you feel will be the most supportive! will be thinking of you and sending lots of good energy your way!
good luck!
