Moving forward in life = Loosing friends?

So couple months ago my life changed forever, I moved in with my bf to where he lives 2 Hours flight away from where I lived at the same time I got pregnant so obviously I stoped drinking and smoking, in the proces I noticed I lost friends like wtf? It's like if my happyness were annoying for them... this is what I chose... How is that so hard to understand? One of my "bestFriends" was pushing me to make an oficial announcement about the baby and stuff and I wasn't ready so she got mad... I told her my reason and she reply with " i don't even care... lucky me is not my life" like wtf does that mean?! Other friends they  don't even talk to me anymore some other make fun of me... wtf is wrong with people?!
