One of my best friends just got a boyfriend. I’m really happy for her, but lately she’s acting all girly and trying too hard to impress him. I was over at her house one day when he was there. We were looking through the paper and she said, “I read the sports section every day.” But I know she doesn’t because I’m always telling her who won the baseball game and how our local football team is doing. My other friends have noticed, too. We want her back the way she was before!
She's going through the new boyfriend phase. You might mention to her what you and your friends have noticed. If she doesn't want to listen, just give her some time to figure things out, and come to her senses.
