Revealing pregnancy

So I told my side of the family that we are pregnant with our 2nd. And I completely regret telling my step mom & biological dad. I was super excited to let them in on our secret. Well my step mom acted disappointed and my dad just brushed it off. Like wtf? I guess growing life in your body isn't enough to get excited about. But when I told my biological mother, two sister and my little brother, they were super happy! I thought my mom would faint! We aren't telling my husband's side cause they are the worst at keeping it a secret. So we'll wait till we have a good ultrasound to go along with it. They'll let everyone know so we're gonna wait until we are ready for the world to know.   But I'm really bummed about revealing this to my step mom and dad. It just really hurt my feelings. And I'll bet everyone that they won't be there for the birth either. They didn't even try to see our first child until about 2 months. I'm trying to focus on just my growing family and not let the bullcrap annoy me. I just needed to rant. Thanks ladies ❤️😲
