help with Inlaws

Abby
i get so frustrated and irritated when my brothers fiancé steals my baby name and always try's to copy everything me & my boyfriend does. Like baby names and going to my doctor, and always asking to borrow my baby stuff. No, i worked my butt off at my job to buy that stuff. She isn't working because she uses the excuse she's pregnant and she can't work. I'm just annoyed.
