Dear Caroline: My current boyfriend’s ex-girlfriend had, and I know this is gross, much bigger boobs than me. I have fairly flat chest. We’ve been together for 2 and a half years, but I recently found out that early in our relationship (about six months) he told one of his friends that he was “glad to have had the chance to be with someone bigger”. boobs before dating someone he likes but has flat chest. And I don’t know how upset it can be.
