Dreams involving infidelity can often reflect feelings of insecurity, betrayal, or fear of loss in a relationship. In your dream, your husband's infidelity and the subsequent actions you took may symbolize your feelings of hurt and anger regarding trust in your relationship. Throwing his clothes out of the window could represent a desire to let go of the emotional burden and reclaim your space or autonomy.

Living in your childhood home might suggest a connection to your past, perhaps indicating that unresolved issues from your upbringing or previous experiences are influencing your current feelings. This setting can also evoke feelings of nostalgia or a longing for comfort during a tumultuous time.

Overall, this dream could be urging you to address your feelings about trust and commitment in your relationship, as well as to reflect on your own emotional needs and boundaries. Consider what aspects of your relationship may need attention and communication to foster healing and understanding.
