I was with a female classmate from highschool and we were kissing even though I am married with children with another woman. In all my dream my classmate were with me all the time
Dreams involving infidelity can be unsettling but it doesn't necessarily reflect a desire to cheat in real life. Often, dreams like this represent a desire for greater connection and intimacy with someone or a certain aspect of oneself. In this particular dream, it's possible that your high school classmate represents a certain innocence or nostalgia for a simpler time in your life. Kissing her may represent a desire to go back to a time when things were easier and less complicated. Alternatively, since you mention that she's a constant presence in your dreams, it's possible that there's a lingering attraction or unresolved feelings towards her. It's important to acknowledge these emotions and work on any underlying issues that might be hindering your happiness in your current relationship. It's ultimately up to you to determine what this dream means to you and how you want to approach the emotions that it brings up.
