Dreams about a past love or someone from your past, especially in the context of a proposal, can evoke a range of emotions and thoughts. Here are some insights to consider:

1. Nostalgia and Reflection: Your dreams may reflect feelings of nostalgia or a desire to revisit certain aspects of your past. The man proposing in your dream might symbolize unresolved feelings or a longing for past experiences.
2. Emotional Connection: The recent reconnection after many years could have triggered memories and emotions that are now manifesting in your dreams. This doesn't necessarily indicate a desire to change your current relationship but may highlight the importance of past connections in shaping who you are today.
3. Current Relationship Satisfaction: Since you mentioned being happily married, the dreams could also be a metaphor for your current relationship. The proposal may symbolize a desire for deeper commitment or connection within your marriage.
4. Dreams Ceasing: The fact that the dreams have stopped may indicate that you have processed these feelings or that the initial emotional responses have settled. It could also suggest that your current relationship is secure and fulfilling, leading to a decrease in those past-related dreams.

Reflecting on your feelings about your marriage and your past interactions may provide additional insights. If these dreams or the emotions they evoke continue to trouble you, consider discussing them with your partner or a trusted friend for further clarity.
