How do you know if he's not over his ex-wife?

You might suspect he isn't over his ex-wife if he frequently brings her up in conversation, expresses lingering feelings for her, or compares you to her. Additionally, if he avoids discussing his past relationships or seems emotionally distant, it could indicate unresolved feelings. Observing his social media activity, such as interactions with her, may also provide clues about his emotional state. Ultimately, open communication with him about his feelings can provide clarity.
