Not letting a kid see their aunt

Jessica

My boyfriend sister is the same age as me. She’s been making some questionable life choices lately which she’s in her early 20s this is the time to experience such things. Well we haven’t seen her for a few months she’s moved in with her cheating boyfriend. She calls today and says “I’m gonna be there in 10 minutes have the baby ready.” And I ask while my boyfriend still on the phone where she’s taking him. And he continues the conversation asking her about the money she was suppose to give him and I ask again where she’s taking the baby. My boyfriends hangs up and tells me to get the baby ready. And I ask again where is she taking the baby and he snaps at me “I don’t know why do you want me to call her back and say no.” And I was like “yes if she’s taking him to Wisconsin or out with her boyfriend.” And now my boyfriend is mad cuz I don’t trust his sister to take our kid. I don’t feel like I should have to apologize for not feeling comfortable letting my son go somewhere.
