How can i help my wife see how beautiful she really is?

Look for her beauty: Inside. No matter how many times you tell her she is beautiful or show her in the mirror that she is, something inside says she is not. Don't push for the insight. Try to hear what she is saying about herself that may cloud her ability to see her beauty. It's very tricky because she most likely will say you are biased, you're her husband. If you can't reach her a counselor may be in order.

Gentle Consistence: It can be hard for some women to accept their good qualities, including their physical beauty. This depends a lot on how they've been treated earlier in their lives. You can treat your wife with love and respect, and compliment her genuinely. Let her know how much you enjoy being with her. If indicated, you can help her get professional help too. There are many ways to let her know you love her.
