I broke up with my boyfriend, who is 29, and I'm 23. I'm feeling unsure about whether to go back to him.

I'm feeling confused and could use some personal advice. We've been apart for seven months after a six-year relationship. Recently, we reconnected, and I can't stop thinking about him. He finally wants to talk after I ended things earlier this year. I keep wondering if I should have tried harder or sought counseling instead. I've started seeing someone new, who is a genuinely good man, but something feels off. I can’t shake thoughts of my ex from my mind, which adds to my confusion about what to do next. Our past had its share of ups and downs, but that's common in relationships. When we met recently, he mentioned he's changed and would like to give things another shot. I agreed, but then I backed out because I was unsure. I don't want to ruin the possibility of rekindling our relationship, but I feel torn about my feelings. What should I do?
