Feeling Lost and Torn

I just got through a messy divorce after six years of marriage. We tried everything, counseling, open communication, but it wasn't enough. I'm now alone in my dorm room at law school, trying to focus on my studies but finding myself lost in thoughts about the past. The break-up was sudden and painful, leaving me questioning every decision I made leading up to it. To cope, I started seeing someone new, someone much younger than me, in her twenties. It felt like a secret romance, forbidden yet exciting. But now, I find myself struggling with guilt over the age gap and our different life stages. We both enjoy exploring playful dynamics that blur lines of authority and comfort, but it's also confusing. Is this normal? Am I just going through a rough patch or is there something more fundamentally wrong here? What advice do you have for someone trying to figure out where they stand after such big changes in their life?
