I’m unsure about what to do: should I stay or should I go?

**Summary:** I lean towards leaving the relationship, but the hope for change makes me hesitate. When I consider staying, I feel anxious and struggle to commit to my partner's desire for one last attempt, as I doubt his ability to truly change. I’m a 25-year-old woman feeling uncertain about my long-term relationship with my partner, who is 23. We’ve been together for nine years, starting from high school. We almost broke up until I discovered I was pregnant, prompting us to stay together for our daughter. Over the years, I’ve been a stay-at-home mom, dedicating myself to caring for both our daughter and him, often at the expense of my own dreams and aspirations. I’ve voiced my need for change countless times, but I haven’t seen any real progress. Despite my hopes for improvement, I’ve felt mentally drained while he believes everything is fine. After expressing my desire for change one last time, he agreed, but the effort lasted only a day before things returned to the same routine. This led me to request a separation, during which he suggested we live together as roommates. While apart, I began feeling an attraction to someone else, which made me realize I may have emotionally checked out of my current relationship. It was painful for both of us, but I eventually accepted that it was over. About two weeks later, he expressed a desire to move out because it hurt too much. But then he asked for one last chance. While I want to support him, I worry that it might be too late. I’m also skeptical about his ability to change this time. My feelings for him revolve around the person he is, not just what he provides—I'd prefer to share a life instead of being two individuals who only connect at the end of the day. When I take time to reflect on how to proceed, staying fills me with panic, fear, and stress. I worry that if this last chance fails, I’ll feel deep resentment towards him. On the other hand, the idea of leaving and starting fresh elsewhere feels scary, but not as overwhelmingly so. Right now, my mind is a jumble, and I feel lost when thinking about my options.
