My little sister constantly says i'm hers
I'm her brother, 20, and she's 14. I've been studying abroad since I was 15, and she's always missed me (I miss her too). We've always had a rather close relationship, and have never fought with each other.
But whenever I tell her about my girlfriend, she loves to nitpick everything about her, and even go as far as saying, "You're mine, I won't let that bitch take you".
I know she's been through some tough times lately (our parents are SUPER strict Christians), but is she a bit too possessive?
