Am I wrong ?

So before I became pregnant his family thought I was non existent not in the sense they didn't know we were together but they didn't have any interest in me . Now everybody wants to call and breath down my neck and I'm like - I don't know you I don't like you get away from me . Not to mention he has a nephew that at 7 or 8(?) still throws tantrums and acts like a spoiled brat . I don't want that influence on my child . Am I wrong for wanting them to keep their distance ? He says I'm being mean :/ . I'm really not even down for my baby staying out anywhere or anything without me until he or she is able to speak . *shrugs my baby my choice .
