am i wrong for wanting boundaries

Natalie

my baby’s father was not involved at all during the 9 months and decided to want to be involved 1 weeks before i gave birth. i didn’t include him in naming our baby and didn’t put him on the birth certificate and now he shows up with his mom to my house whenever they decide they wanna see her without asking for permission what should i do if i can’t get them off my back they wanna be in my house every day of the week.
