Dreaming about an ex getting married can evoke a range of emotions and interpretations. Here are a few insights to consider:

1. Unresolved Feelings: This dream may suggest that you still have unresolved feelings about your past relationship. It could indicate that you are processing emotions related to your breakup.
2. Closure: Alternatively, it might symbolize a sense of closure or acceptance regarding the end of that relationship. Seeing an ex move on can signify your own journey towards healing.
3. Comparisons: You might be comparing your current relationship status with your ex’s. This could reflect your feelings about love, commitment, or where you stand in your own romantic life.
4. Fear of Change: If you have fears about commitment or change, this dream could represent those anxieties manifesting in your subconscious.
5. Symbol of New Beginnings: Sometimes, an ex getting married can symbolize new beginnings in your own life, perhaps pointing towards personal growth or new relationships.

Reflect on your current feelings and circumstances to gain further insight into what this dream may mean for you personally. Consider journaling your thoughts or discussing them with someone you trust to explore these feelings deeper.
