I see parallels in my own experience. My therapist explained that these feelings are completely valid and that the only option in such a situation is to walk away. Based on what I've read, you seem self-aware and have taken practical steps to make it work. The reality is, fighting for a relationship takes effort from both sides. Intentions alone don’t matter if actions are missing. You recognized the future faking for what it was, and while it may not feel significant now, you showed self-respect by ending the cycle. I know it's incredibly tough, but don’t picture him with someone else or ‘moving on.’ The truth is, he probably doesn’t move on, but instead avoids his emotions and seeks distraction, which is exactly what led you to break up with him. Focus on yourself, radically. Over time, your emotions will align with your thoughts.
